(could start from SeaBIOS CSM and then think about how to turn it into a separate loadable EFI module) and what grub does is very far from it. Heck, you would be basiclly making loadable CSM module!

Newer versions of Windows XP (that is, with Service Pack 2 or SP2 installed).

It should be possible to make full-blown BIOS emulation using similar 'fakebios' technique, probably, but that would be quite an undertaking, most likely year or two of work. Rather, IE for Mac uses a Netscape plug-in emulator to read

System Utilities downloads - ANDY OS by and many more programs are available for instant. That's most definitely not a full-blown BIOS emulation (since only INT10 is provided, nothing else), but enough to make old Linux video drivers happy.

Note: since you are only grabbing address of INT10 and Video BIOS (but not other BIOS-provided vectors and not other BIOSes) and said BIOS is never initialized in that scenario.

This works since on Macs, apparently, these regions of memory are shadowed and not used in EFI mode.

Document which you have refered explains things in very precise detauls: you boot in BIOS mode, dump contents of $00040:$00043 and $C0000:$CFFFF regions of memory, then, in EFI mode, put them back in proper place.
