full kernel 3.5rc2 log

Screen on my Samsung R50 notebook with AMD Mobility Radeon X300 (RV370 chipset)
become completely unusable after resume (watch screenshots). I've tested
different kernels from 2.6.32 till 3.5rc2. Just the same thing. The thing
happens only with KMS turned on. I have tried suspend from X (Xfce) and from
console (using pm-suspend).


I repeatedly get following errors in kernel log after resume:

I recognize that I have really old notebook, but It has enough power for my
tasks so it will be good to use KMS on it cause I loose a lot of features of X
without it.
