That kernel is insanely old.  Please use a current version.  There are
still known issues with 855 chips though.
Now it's:
$ cat /proc/version
Linux version 2.6.32-5-686 (Debian 2.6.32-30) (ben@decadent.org.uk) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Wed Jan 12 04:01:41 UTC 2011

After upgrade акщь 18/01/2011 (I didn't upgrade the system since the end of december) the situation has deteriorated markedly - X crashes permanently, but now I can get to the console. The only error message in /var/log/Xorg.0.log is:
Fatal server error:
Failed to submit batchbuffer: Input/output error

Also I've got message:
X: ../../src/i830_batchbuffer.h:79: intel_batch_emit_dword: Assertion
`pI830->batch_ptr != ((void *)0)' failed.

What else can I do to help in resolving the problem?
