Hmm... looking at recent changes in the DRI ati-4-0-1 branch, I spotted the

- Added minimal PCI support (PIO only with no VBs)
  - Autodetect PCI cards -- selets CCE PIO mode and disables VBs
  - Kernel module will now build without AGP support (for PCI cards only)

Is this good news? If yes, let's hope it'll be in 4.0.1 ...

Of course, but we are living in an x86 centric world *sigh*

Cool! What about the DRM module, any idea if it works?
