Okay, so that answers the question about if -fglrx supports EXA. Guess not.
Another thing to try I found in googling around a bit, please try adding:
Section "ServerFlags" Option "AIGLX" "off" EndSection
to your xorg.conf
Apparently AIGLX, which isn't supported on fglrx, kicks into software rendering mode when it finds itself active on a system that doesn't support what it needs for HW rendering.
