[mythtv-users] Strange X behavior with nvidia drivers

I am currently going through an OS upgrade cycle to FC3.  One of my
machines has a Chaintech 7nif2 igp system board 512mb XP 3200+.  This
machine has been my test box for mythtv.  I was planning to switch it
over to my primary work station and change my work station over to a
mythtv server.  After installing FC3 (everything) and running apt-get
dist-upgrade, install KDE 3.3, latest FC3 kernel, and nvidia drivers.  I
noticed something odd.  I usually run my workstation at 1280x1024.  The
machine with the 7nif2 has always been run at 1024x768.  Now I want it
to run at 1280x1024, it does so using the nv driver.  The problem is
that if I use the nvidia driver 6629 I only get 1024x768 on the display
with a virtual 1280x1024.  Is this a known issue or am I missing
something blindingly obvious?

Change this 
	Driver      "nvidia"
to this
	Driver      "nv"
and you get 1280x1024 on the display.

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.

# If you have a US Microsoft Natural keyboard, you can use:
#       Option  "XkbModel"      "microsoft"
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#       Option  "XkbLayout"     "de"
# or:
#       Option  "XkbLayout"     "de"
#       Option  "XkbVariant"    "nodeadkeys"
# If you'd like to switch the positions of your capslock and

#       Option  "XkbOptions"    "ctrl:swapcaps"
# Or if you just want both to be control, use:
#       Option  "XkbOptions"    "ctrl:nocaps"
