I just talked to upstream developers about this, they think it is very
hard to fix. It is a firmware bug and that would require lots of work in
the nv driver (and it's not going to happen). I am tagging this bug as
"wontfix" unfortunately then.
They also said that if you're using a DVI cable, you should try a VGA
one instead. The way the card drives the monitor is very different. The
"too small panel size" problem that prevents 1680x1050 from being
accepted on DVI should not occur with VGA.
