2.6.32-rc3-git display goes off with i915.powersave=1

Dear all,

on my Samsung NC10 the latest kernel i915 driver with powersaving
enabled causes the dissplay to go randomly black (or white) after a
random time (few minutes usually).

The only way to recover from this is a suspend to ram cycle....

I've upgraded to the latest xorg-intel driver to see if it works with
that one - but no it does not. However, setting powersave=0 makes things
work again..

And it looks like I am not alone:

will be utterly fantastic. -- Arthur C. Clarke, 1962
