This might be a soloution to your trouble.
Take a look at your XF86Conf-4, at the section "Screen". You have got the
depths listed but you seems to not having the "modes" listed for the
proeriate depths.
It sould look somthing like this:(the section in my XF86Conf-4)
"
Section "Screen"
Identifier "Default Screen"
Device "GeForce 2 GTS"
Monitor "___:ffff"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 8
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 15
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

Swap my GeForce with your Generic Video Card and my ___:ffff with your Generic
Screen.
Beware! If your screen was autodetected, as it looks like, you have got a low
HorizSync and VertRefresh rate. I am a bit unsure, but my screen is 30-70(HS)
and 50-120(VR) and I am not alowed to have more than 1280x1024 at 60Hz,
neither in linux or windows. It looks like your Windows has gone a bit far if
you have had 1152x867 at 76 Hz. Try 1024x768 at 72Hz(or a bit more).
72 Hz is the lower limit for your eye to registrating flickering. Everything
above will look "solid".
