As mentioned in the referenced bug report, you can disable radeonfb with
video=radeonfb:off or disable KMS with radeon.modeset=0.
The problems with KMS mentioned in that report weren't substantiated
with specific information. The biggest known gotchas right now are:
* radeon.agpmode=1 (or even radeon.agpmode=-1) may be needed for
KMS to be stable on PowerMacs.
* On laptops there's no backlight control and no suspend to RAM
support yet.
