My 9600GT with modeset=1 turns my monitor off, no lockups or anything but I
can't see anything. Here's a dmesg when issuing modeset=1 from console

Can you file a separate bug for this please?  I'm working on getting the
kernel
modesetting stuff into shape, so I'll get to it!

In the new bug, if you load the drm module with debugging enabled it'll give
better info as to what's going on:
 modprobe drm debug=1
 modprobe nouveau modeset=1

Thanks.
