dmesg

Kernel oops booting with radeon kms
Comment 1 Alex Deucher 2011-02-01 10:51:11 UTC 
I suspect this is a problem with agpgart-via.  Does booting with radeon.agpmode=-1 on the kernel command line in grub help?

dmesg agpmode=-1

No, doesn't help.
Comment 3 Alex Deucher 2011-02-01 15:38:18 UTC 
Can you attach the output of 'lspci -vnn' ?

drm patch

This drm patch will fix it.  The 0x4243 pci id is a bridge device, not a gpu.
