Since 2.6.39 and also with 3.0-rc2, when starting glxgears, my machine freezes
(as in "even caps/lock does not respond anymore"). Despite that, X-Server and
2D-stuff (shells, browsers) work fine all the time. Bisecting resulted in:
8410ea3b95d105a5be5db501656f44bbb91197c1 is the first bad commit

drm: rework PCI/platform driver interface.
This abstracts the pci/platform interface out a step further,
we can go further but this is far enough for now to allow USB
to be plugged in.
The drivers now just call the init code directly for their
device type.

I can confirm that 2.6.38-rc5 worked fine and 2.6.39 with this commit reverted
(and manually disabled drm_usb) works fine, too. Seems really to be the
culprit.
Note: I don't have DRM_RADEON_KMS enabled, if I do, there is no crash (but the
framerate drops from 260fps to 13 fps).
