Screen res too low on Thinkpad i1400

I'm running Debian Etch on an old thinkpad i1400, but the maximum resolution available in the Gnome screen res dialog is 800x600. The display is capable of 1024x768. I went through the xorg.conf file and removed all the 800x600 and 600x480 modes, but that didn't work. I looked through the xorg.log file and found that the neomagic driver says that there is not enough memory for 1024x768 and over. This is, of course, not true. I have Windows XP running on the same system and it displays 1024x768 just fine! Is there some way to force X to use the propper resolution, no matter what it thinks?

I think that you adjusted nothing regarding the type of Monitor.
Thats why Ubuntu (I am not a Ubuntu man :P ) but it's standard that x configures
a 800x600 Monitor so you will never be able to drive a screen resolution of 1024x768 of course. So what you have to do is just to choose a huger LCD Display type.
In your /etc/X11/xorg.conf the important section is Section "Monitor"

so maybe this xorg.conf will fit your needs:

Section "Monitor"

### Comment all HorizSync and VertSync values to use DDC:
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Dell 1024x768 Laptop Display Panel"
### Comment all HorizSync and VertSync values to use DDC:
HorizSync 31.5 - 48.5
VertRefresh 59.0 - 75.0
Option "dpms"

Section "Device"
Identifier "Videocard0"
Driver "i810"
VendorName "Videocard vendor"
BoardName "Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller"

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480"
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
