Removing this altogether as Excalibur stated will not affect system performance, and is in fact what you will want to do.

This is part of APM or ACPI...I suggest ACPI unless you are using a laptop. See the thread below for info on how to do this...

This will allow the machine to power off when the shutdown command is issued...as far as a blank screen? That's another issue. This chip does not affect this. I would think it has something to do with X and possbly framebuffer support in the console.

Can I just remove them from the .config file and compile from there?

No...you need to cd /usr/src/linux
then make menuconfig
then find the options and uncheck them
then exit and save
then recompile

blacklist
 

If you don't want to do the recompile you can place i810-tco and i810_rng in the /etc/hotplug/blacklist file to prevent them from being loaded. (i810_rng trying to load gave me error messages on start up ) I just saw this in a recent post. Thanks to everyone though cause I was still able to do some learning about how to recompile anyway :)

Re: slackware-current problem
 

I have the same to you.I have the 845 chips and nvidia gf3 .I has the "full install" too.And I say "yes"to hotplug suppets.
Then the computer auto reboot after the system complete load the kernel(appear login prompt or login as anyone).
I asked this quesstion in the forum and have a answer,"edit the /etc/hotplug/blacklist ,append the 'i810_rng'".I do so,the errors disappear,but the system still auto reboot.
I find the hotplug actully work with simulate pci cards hotplug to detect and load proper modulers when boot(see /etc/rc.d/rc.hotplug).So I do as follow
boot and login, lsmod >/root/tmp.txt
boot from slackware and mount /dev/hxx /mnt
mv /mnt/etc/rc.d/rc.hotplug /mnt/etc/rc.d/bakrc.hotplug
mv /mnt/etc/rc.d/rc.modules /mnt/etc/rc.d/bakrc.modules
edit /mnt/etc/rc.d/rc.modules to activate proper modules in the /mnt/root/tmp.txt
Now I can enjoy myself.
Good luckly!
