xorg-x11-drv-fglrx and kmod-fglrx have been updated to the 9.4 beta
which is originally found in Ubuntu Jaunty (9.04) and have been patched
for 2.6.29, so it should be working well with Fedora 11. However, one of
the side effects of the 2.6.29 patch is that fglrx repeats the same few
errors over and over again into /var/log/messages and /var/log/dmesg
(the error itself seems harmless, as the driver continues to function
correctly). I recommend that you check on these files every few days to
make sure they aren't growing too quickly.
