Googled like a madman and found the following slightly related bits and pieces.
--- >From http://lkml.org/lkml/2004/11/14/24 "You are building AGP as a module with DRM as a built-in ,the DRM cannot use the AGP if it is not built in also" Seems not to be the case here; everything is modular. --- >From https://bugs.freedesktop.org/show_bug.cgi?id=9442 "These are just symptoms of the DRI not being enabled." Hmm. >From same place "... disabling multithreaded pci discovery in the kernel made things work again. ... It seems that the AGPGart module is loaded 'in parallel' with the DRI module and this explodes when Xorg tries to enable DRI." Unloading AGP, DRM and Radeon modules and then reloading them manually, in sequence, didn't fix things. So this *seems* to not be it either? How do I disable multithreaded PCI discovery in Ubuntu? --- >From http://lkml.org/lkml/2005/9/10/78 "You're missing your AGP backend" That certainly seems to go hand-in-hand with the "AGP not available" message in the X log. Doesn't fit very well with the agp modules actually being visible in lsmod though. ** Summary changed: - ATI Radeon 8500 unworkable 3D + ATI Radeon 8500 unworkable 3D - "RADEON(0): [agp] AGP failed to initialize.
