Resolution too high with 7-RC1, nVidia, xorg

[Xn Nooby]

I was able to temporarily change the resolution using the "xrandr -s
1024x768" command - but "xvidtune -show" still displayed a modeline
that begins with "1280x1024".  I copied that modeline to my xorg.conf,
and manually changed the resolution, but I did not fool it.  It was
great to see the screen at 1024x768, so I know it can do it.

I added a "1280x1024" mode to my xorg.conf display list, and it not
change the behavior.

I was able to get 1280x960 by increasing the lower range for
VertRefresh to 70, and was able to get 800x600 by increasing it to 75.
I then played around with various other VertRefresh values, but had no
luck.  I also tried the Horizontal values, but the did not help.  I'm
using a flat-panel screen, so I don't think I can hurt it. I hope!

xrandr worked, though my IceWM menubar fell off my screen. xvidtune
could probaly fix that, if I could get the ModeLine command to have an
effect.
