These steps are ok, I don't know why it won't work with your box, except it's maybe in conflict with default radeon driver.
Maybe you should try to start X from runlevel 3, with startx command. That way we should get some additional informations.

I can see from your xorg.conf that you have two device sections:

Looks like both drivers are "on".

Well, if you want to give it another try, backup and remove that xorg.conf, removepkg old radeon driver, just in case, boot the machine in runlevel 3, install fglrx package again, and let it create new xorg.conf with aticonfig --initial. Then you can go for another reboot in runlevel 3, and try with startx.

Actually, you can see in his ServerLayout section that only the Screen section using fglrx is listed, so his xorg.cont file is not causing radeon to get loaded.

Perhaps, however, the radeon kernel module is still getting blackloaded. I thought the fglrx installer would blacklist it, but perhaps the slackware packages don't?

Tried again, same problem. Will try aagain tomorow.
I have a 4870 if that helps.

I use it always the direct way (without making the package, just let the installer do his work) and it blacklists automatically and just works.
By the way, blacklisting doesn't mean that the module won't be loaded at all, it just means that it isn't loaded at boot time. It may be possible that Xorg loads it nonetheless if it is in the configuration file, even if it doesn't use it (not sure about that).

I don't know about bare installer, but packaged driver worked for me when I had ATi card several months ago. And I've made it just like I described earlier in my posts. So.. I don't know what could be the problem here, especially if default driver package is removed from system.
That xorg.conf he posted is real mess. Apparently, catalist just appended its new settings to the default old ones, and that could be the problem, but again.. if he made new xorg.conf with aticonfig --initial after default driver was removed, then it should be ok.

It's a very well known bug to me as well. After creating and installing package driver will not work. Just remove your ati driver package you created and installed, make sure that everything was removed and no driver module (fglrx) loaded, then install driver using installer, without package creation. Then do:

and everything should work.

You can uninstall ati proprietary driver installed with an ati installer by command:

if I'm not mistaken. So, no need for package. Installing software without package is not Slackware style, but at least it works.

Ah, almost forgot, maybe you will have to load module manually at first time:

Well, there shouldn't be any difference between packaged and non-packaged installer, it's the same software. Packaged form is just "cleaner" for installing and uninstalling. I've had Radeon HD4350 card several months ago, with proprietary driver installed the way I mentioned before, and there were no bugs or problems with it. Also, tere was no need for "modprobe fglrx", everything went well.

cefege, is this an AGP card or is it PCIe?

Do you have another computer on the same network? If so, can you remotely log into your Slackware box after this problem happens? That way you can look at the Xorg log file and kernel messages to see if there are any errors.

Black Screen when starting X? I ran into this issue a while back and this is what i did to fix it.

Blacklist the radeon driver by editing /etc/modprobe.d/blacklist.conf

first "rmmod radeon" then add "blacklist radeon" without quotations to the list, you will need to be root/su to edit this file

then modprobe fglrx, aticonfig --initial and you should be set. a reboot may be required.

Andersen, yes, there shouldn't be difference in driver work between package and installation made by installer, but only in theory. I saw some threads in forums about this problem, and yes not everyone gets black screen with package installation, but those who got it sometimes can solve this just by installing driver with installer instead of package. I don't remember from which version of driver this bug started, I think it was first driver version which supported building packages for slackware 13.1, if I'm not mistaken, but since then I can get driver to work only by installing it with installer, with package installation I'm just getting black screen and even termination of x session (ctrl-alt-backspace) is not working, only resetting or switching off computer works, sometimes I could restart computer with ctrl-alt-delete, but just after quite a long while by pressing ctrl-alt-delete several times. I have Radeon hd 5570.

Yes, you do not have to do modprobe for fglrx module if you are installing from package, as package installation script will do it during installation.

Update:
I installed ati proprietary drivers
amd-driver-installer-12-1-x86.x86_64
I just installed it manually, didn't make it slackbuild.

Everything boots ok, I can use X.
However I can't use anything 3d. Any 3d screensaver doesn't work anymore.
Tried playing minecraft( which worked before with open source drivers).

I'm no expert but this is the problem right?

Yeah, the error is pretty self explanatory. Sounds like the fglrx kernel module never got built/installed. What is the output of:
