Having exhausted all options, I went and tried to find a solution for
getting the media reader to work (it still doesn't :) ) and in the
process, found a website that describes howto get the display to go up
to 1600x1200.  I haven't tried such a feat yet and am not too anxious to
do so, but the solution to that problem was setting the NV_reg_Mobile
option.  Loading the nvidia module like this:

modprobe nvidia NVreg_Mobile=1

Will bring the X server right up.  Initially, I set it to NVreg_Mobile=0
and it returned to the console.  You can probably imagine the excitement
that set in at that point: the laptop had NOT hardlocked.  Apparantly,
NVreg_Mobile=1 needs to be set with mobile nvidia GPUs.  Perhaps a minor
change to Debian documentation could reflect this.

Please repeat and confirm that this fixes the problem.

This also seems to solve the problem for me.  If I boot (either without
X, or using "nv"), then modprobe nvidia with these options, I can then
start X (with "nvidia").

One outstanding problem: how can I force the module to the loaded with
this option at boot time?  I thought I just needed to put
nvidia NVreg_Mobile=1
in /etc/modules, but this doesn't seem to work.

Further comment: I'm not sure if I am supposed to be using nvidia-legacy
packages instead, but I can't solve all dependencies to install these on
my system (just upgraded to latest 2.6.16 and X.org 7.0).

Thanks,
