Okay, I see now. The problem is that the VESA standard has stood
still since the death of DOS. Now more sophisticated hardware
detection and configuration is necessary, bypassing the BIOS entirely.
(Apart from some minimal low resolution support for BIOS
configuration, booting, and screens displayed prior to the OS'es
hardware detection, and loading of drivers.) The BIOS on this machine
uses 640x480 for the boot screen by the way, and Win-XP uses a low
resolution Splash screen before it boots (rebooting into Win-XP to
make a note of what resolution it uses would be tricky since the time
window to gather the information is rather short (it is an AMD64-x2
4200+ with 3GB of ram, and boots rather quickly.)

The bottom line as I see it is that unless the install is willing to
default to 1024x768 or below, the days of relying on the BIOS to
properly configure your video card for the monitor are numbered.
Further updates to the VESA standard to take into account new video
cards and monitors are not very likely.
