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.

This looks similar to the xchat corruptions I see (on i855).

Have a look at #34980 (also 945 family) and #35460 on bugs.freedesktop.org.

Yes, the similar symptoms have also been reported in Ubuntu

https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/737900

I have yet another machine, with an older chipset - VGA compatible 
controller: Intel Corporation 82865G Integrated Graphics Controller (rev 
02) no corruptions occur in this machine.

Ooops, sorry, today I have noticed the same problems on the machine with 
Intel Corporation 82865G Integrated Graphics Controller (rev 02).
