Reports are different it's easy to see, but not much.
I put in init :-
modprobe drm debug=255
and rebuilt initrd . It's for sure.
Maybe change some other lines ?

Example here:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/radeondebug/dmesg-2.6.31.4-2009-10-21-with-ttm-patch.txt
do "grep -i drm dmesg-2.6.31.4-2009-10-21-with-ttm-patch.txt" and you'll
notice there is a lot more debug information..
