Comment 5 for bug 36316

Forgot to post back results... I added the PCI ID to the radeon driver and rebuilt the kernel. No worky. It just pukes it's guts out. Nothing on screen. I've since learned that the output engine is very different, and the 2D core isn't even Radeon-based in this chipset.

If I use the 'fglrx' driver from linux-restricted-modules (>=2.6.15.9.1), and cheat by telling the binary fglrx driver (which is >= 8.24.8) that the Chip ID is 0x71c5 in the xorg.conf file, then it works flawlessly.
