The log contains all the info required I believe. It's here: http://www.pastebin.ca/1296863
Did a fresh install, aticonfig --initial, eselect opengl set ati (gentoo-specific stuff). startx would bring a black screen and Ctrl - Alt - Backspace would hang the system.
Any ideas are welcome. TIA.
Rebuilding doesn't help, there's a single fglrx.ko available.
# modprobe fglrx
FATAL: Error inserting fglrx (/lib/modules/2.6.27-gentoo-r7/video/fglrx.ko): Invalid module format
