I believe this is a different bug (and I think it's in Bugzilla as such
against the xorg driver package, but I don't have the number handy).
The nvidia binary drivers work with my T61 (Quadro NVS 140M) modulo this
thread's intermittent freeze on resume (and worked fine before the
latest kernel).  It works except for an annoying check on the second CPU
on resume on a T61p.

The nv drivers do not resume properly on either machine, and have not
(in F8 and F9) since F8 was released.  I don't really understand why
they can't get it to work, as the plain vesa drivers suspends and
resumes just fine, but the backlight never goes off when the screen is
idle.
