I've solved bug #532579 "Segfault in libint10 when restarting xserver or using xorg.conf" - the vesa module is needed to check the VBE VESA settings.
This enhanced xorg.conf provides the workaround for full 1024x768 on Lucid:
----- /etc/X11/xorg.conf ----- Section "Module" Load "vesa" EndSection
Section "Device" Identifier "Intel Corporation 82815 CGC" Driver "intel" EndSection
Section "Monitor" Identifier "LCD Panel 1024x768" Option "DPMS" HorizSync 28-64 VertRefresh 43-60 EndSection
Section "Screen" Identifier "Default Screen" Device "Intel Corporation 82815 CGC" Monitor "LCD Panel 1024x768" DefaultDepth 16 SubSection "Display" Modes "1024x768" EndSubSection EndSection
Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" EndSection
