I also get occasional complete crashes of the X server, about once every
2 weeks (average).  I guess that's a different bug, but they might be
related.  It is very annoying as all applications are killed instantly.

When that happens, it tries to restart X and that always fails - so
eventually it stops trying, and offers to run in "low graphics mode".
However, once, it didn't even do that, instead it had the appearance of
repeatedly trying to restart X forever.

That suggests the hardware, or the kernel, can get into a state where
the X driver cannot reinitialise it.

I have checked whether booting with/without KMS ("nomodeset" to the
kernel) makes a difference.  It certainly affects the bootup screen
(it's obviously not been tested much with nomodeset ;-) ), but:

The X display issues - this block pixel corruption, and occasional
crashes - are the same with and without KMS.  So it can probably be
ruled out as the cause.
