OK, not a problem for beeing a newbie, i'm also one
The one it is to be changed is located in /etc/X11, the others, to be frankly, don't know what they are
1st:
log as root and enter the kernel directory (usually at /usr/src/linux-2.20....
Type make menuconfig
at the end of the menu, there's an option for saving the kernel config into a file, do that and save it
Download the "new" kernel amb descompress it at /usr/src
enter the new kernel directory
Type make menuconfig
at the end, there's an option for LOADING a kernel conf, do that
exit the menu kernel saving the options
type make dep
type make bzImage modules modules_install
2nd:
Copy (usr/src/linux-2.4.2*/)arch/i386/boot/bzImage to /boot/vmlinuz.new (don't overwrite the one you have, for security)
Copy also System.map to /boot/System.map.new
3rd:
Depending wich boot loader you have, there are thing to do. If you use grub, you must enter a new line in /boot/grub/menu.lst, so edit the file and copy the same things you have for linux label, but in this case, tell to boot vmlinuz.new instead of vmlinuz.
If you have lilo, better look to man page, cause i don't use it and i don't know how it works
4.- Reboot your machine and boot the new kernel
5.- run the ATI driver rpm as root with the flag --force
6.- Edit the XF86Config file
7.- Enjoy
Hope it helps, feel free to ask more, because i know it is a bit difficult for a newbie
