Subject: Screen corrupted in Xorg with KMS on 945GM/GMS, 943/940GML chipset
 with kernel 2.6.38.2

After I've upgraded my kernel to 2.6.38.2, I started to experience very 
often screen corruption
in X (it happened also earlier with 2.6.37.3, but now is very often.
Hardware seems to be OK. I attach  sample screendumps, configuration of 
my kernel, log
of the X server and output of the lspci command.
