I had a similar problem trying to set 1400x1050 on a Siemens Fujitsu Laptop. The fix for me, was to use 915 resolution from http://www.geocities.com/stomljen/ as it seems the Intel video bios has a limited set of resolution modes
Hope this helps

Dean,
THanks I have 1 question. on centso 4.2 X starts real early... Where do you run the 915resolution command? I put it in rc.local and it did not seem to work.
THanks,
