Sounds like a problem I'm having with the recent kernels on
an HP 8430 laptop with an ATI video chip.  The effect is
comparable to vertical hold problems on TVs of yesteryear,
only super fast.  Only the original kernel from the DVD
(2.6.31? - I'm not at the machine right now) provides
stable video.

Fortunately, the updater only seems to overwrite the later
kernels and leaves this one alone.  No idea where this 
behavior comes from, but it suits me well.

I'll be watching this thread.  Please let us know if you
figure it out.
