It gives me a kernel panic at boot if I have CONFIG_FB_RADEON
enabled. If I also have CONFIG_FRAMEBUFFER_CONSOLE enabled, I get this
output:

        Unable to handle kernel NULL pointer dereference at virtual address 00000000
        ...
        PREEMPT
        ...
        EIP is a strncpy_from_user+0x33/0x47

        ...
        Kernel panic - not syncing: Attempted to kill init!

If I don't have CONFIG_FRAMEBUFFER_CONSOLE enabled, I get a screen
with random junk and some blinking colored boxes, and the machine
hangs.

2.6.11-rc3 doesn't have this problem. When I boot that kernel, I get
these messages during boot:
