Similar problem with the latest 2.6.32 kernel (I was using 2.6.31
until now).
* If nouveau is blacklisted and /etc/X11/xorg.conf selects the nv
driver, then the problem is exactly the same after a suspend/resume:
the screen remains completely off.
* If nouveau isn't blacklisted and /etc/X11/xorg.conf is removed
(so that the nouveau driver is used by X), then the screen is
switched on after a suspend/resume, but it is not restored: it
is gray and the bottom part of the screen flickers.
Basically this means that on this laptop, Debian is not usable
without the proprietary nvidia drivers (the suspend/resume feature
being crucial for a laptop).
