I tried git-bisect all the way back to 3.0, with the same result
I currently have 3.1.2
If I build the kernel without Radeon KMS support, everything boots
successfully, but Xorg reports that the Radeon driver needs KMS, so reverts to
VESA and then everything is ok.
When I enable KMS, the screen blacks out during the boot process, but I can
login in using ssh
