I don't think that you can tell the BIOS to fake its memory count, and
Windows talks directly to the BIOS during boot to get the memory total
(afaik). If it were Linux, *BSD, or a Mach-based kernel, then you could,
either by modifying GRUB's idea of the memory layout, or by just passing
an arg (like the Linux kernel's 'mem=' parameter).
