How can I do that? And how can I configure 16 bpp?

I tried

Section "Screen"
         Identifier      "Default Screen"
         Device          "Intel Corporation Mobile 915GM/GMS/910GML 
Express Graphics Controller"
         Monitor         "Generic Monitor"
         DefaultDepth    16
         SubSection "Display"
                 Depth           16
                 Modes           "1920x1968"
         EndSubSection
EndSection

but this does not work.

Thanks for the notice. My framebuffer size will stay within those limits 
and 3D is not that important for me (except Google Earth... :-)
