Intel Graphics card and a kernel older than 2.6. 31?

I had the same or a similar problem with an Intel 945GM and a 2.6.28 kernel.
After a while I saw extremly short and rare "twiching" and after a couple of 
those the screen went black.

Switching to a virtual console trough, e.g. CTRL+ALT+F1 still works and there 
is output there, just not any GUI anymore.

shutdown + restart helped for a while again.

Problem got fixed when I updated to an 2.6.31 kernel (might already work with 
any version inbetween, those are the two I have tested with).

I can still reproduce this reliably when booting the old kernel, so it most is 
a problem of that kernel's intel driver.
