I also noticed that problem. Most times when I start my mythbuntu machine I have no 3D accelaration:

(WW) RADEON(0): [agp] AGP not available
(EE) RADEON(0): [agp] AGP failed to initialize. Disabling the DRI.
(WW) RADEON(0): Direct rendering disabled

And yes, it is caused by drm and radeon drivers loaded before agpgart module.

Sometimes it is possible to stop gdm service, then unload radeon, drm and ttm kernel modules, load them again and get 3D acceleration working. But sometimes I get only black screen and top shows that Xorg is eating almost 100% of my cpu.

Problem seems to be similar to describe in bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/430694

My machine is an AMD Sempron 2400+ / VIA KT600 based desktop pc with Radeon 8500DV (R200) graphics.
