This worked correctly with Hardy (see attached configuration file)
Upgraded from latest Hardy to Intrepid on 2008-10-09, using xserver-
When run with old xorg.conf (from Hardy), X loads the correct driver, but terminates with "no screens found".
X -configure produces a minimal xorg.conf that works - but only at 1152x864:
% xrandr
Screen 0: minimum 320 x 200, current 1152 x 864, maximum 1360 x 1360
VGA disconnected (normal left inverted right x axis y axis)
TMDS-1 connected 1152x864+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1360x768 59.8
1152x864 60.0*
1024x768 60.0
800x600 60.3
640x480 59.9
Using the vesa driver, I get full resolution (1600x1200) but obviously no acceleration.

The failsafe configuration looks like this:
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection
The auto-generated configuration file is the same minus the 'Driver "vesa"' line.
