That's not actually different.  X drivers (with a bare handful of
exceptions, rage128 not among them) don't consider PCI revision when
driving a display, only vendor and device ID.

Try this driver build:

http://kojipkgs.fedoraproject.org/packages/xorg-x11-drv-r128/6.8.1/5.fc15/

Download that on the live system, install it, and then log out of X and
back in so the server will restart and pick up the new driver.
