working dmesg drm-fixes

Just put my RV670 AGP back in an old box that's been running a r300 for the
past 6 months.

Booting with drm-fixes kernel works, drm-next fails - I loose display as soon
as I modprobe radeon, sysrq works. Exact line used =

modprobe radeon modeset=1 agpmode=8 no_wb=1

agpmode=-1 doesn't help.

dmesg from working and log from fail attached.
