I have tried the following drivers on FC2:
They all worked. (using the version intended for Xfree 4.3.0) HOWEVER.
3.2.8 required a kernel recompile (2.6.6) and this patch: http://members.lycos.co.uk/irtehclod/vmalloc.patch
3.7.6 required these patches be applied:
3.9.0 required this patch:
All the patches are to be applied to the /lib/modules/fglrx/build_mod directory
eg when in that directory patch -p1 < /home/path/to/particular.patch
So basically to install 3.7.6 or 3.9.0 (ask me for 3.2.8 directions):
open a terminal
rpm -Uvh --force fglrxwhateverversion.rpm
apply those patches as stated above
sh make.sh (this should flash lots of stuff by, but should work)
fglrxconfig (this is the final config bit, answer the questions correctly (in fedora, the mouse location is /dev/input/mice) , and answer yes when asked if you want to write it to disk)
mv xorg.conf xorg.olddrivers.conf (back up the old xorg file, if stuff goes wrong, rename this back to xorg.conf)
mv XF86Config-4 xorg.conf
Now reboot X/your PC.
Please please print these instructions out, they are what I have gathered from a week of playing with ati drivers. They should work well.
EDIT: If you use SMP, please don't use this instructions, as I can't say that they'll work. I only have one p4 here!
