Bug 436690

Description of problem:
I seem to be unable to get 1400x1050 on the build-in laptop screen. It's a
Latitude D505 (BIOS A09), but I guess what matters here is:
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated
Graphics Device (rev 02)

Version-Release number of selected component (if applicable):
xorg-x11-drv-i810-2.1.1-7.fc8

How reproducible:
always

Steps to Reproduce:
0. set 915resolution up so that 1400x1050 is listed as mode 3c
1. remove /etc/X11/xorg.conf
2. run s-c-display
3. select i810 driver
4. startx (selecting Quit when told that running X as root is very dumb indeed)
5. display comes up at 1024
6. re-do steps 1-4 but with intel driver
  
Actual results:
xorg will only come up at 1024x768.
 - i810 driver nags that it just does not know 1400x1050 and the relevant modes
show up as follows "Mode: 3c (0x0)" in the log
 - intel driver nags about sync out of range
 - explicitly adding the monitor type in s-c-display dos not help
 - making a modeline with gtf does not help (it seems to be ignored)




Expected results:
after setting the mode with 915resolution I was expecting the machine to be able
to use the mode
