Low screen resolution, IO error reading EDID

I installed Ubuntu 9.10 yesterday, and I'm having a problem with screen resolution, namely, that the available resolutions are lower than what my setup is capable of (my preferred resolution is 1280x1024). I have the Nvidia GeForce 210 video card running in a Dell Dimension 4700. I have installed the proprietary Nvidia driver (185.18.36). I'm wondering if the problem may be with a failure to read the EDID file? I'm really jazzed about Ubuntu, just hoping to solve this issue. Thanks!!!

a) Here's what I get when I run xrandr:

Screen 0: minimum 320 x 240, current 1152 x 864, maximum 1152 x 864
default connected 1152x864+0+0 0mm x 0mm
   1024x768 50.0 60.0
   800x600 51.0 52.0 53.0
   680x384 54.0 55.0
   640x480 56.0
   512x384 57.0
   400x300 58.0
   320x240 59.0
   1152x864 60.0*

b) Here's the Xorg.0.log file:
