The problem happens also under 2.6.34, every two to three days. Did not 
test mplayer/gl driver.

But I found http://bugs.freedesktop.org/show_bug.cgi?id=26358
which looks very similar to the problems I experience. Currently trying 
with new_pll=0 and it looks promising (ok, problems that occur ever two and 
some days are hard to test, but I could not reproduce now for around four 
days...)
