Mike Smith 7880e8b2d5 Mindbogglingly, many BIOS vendors expect to be able to load %ds with 
0x40 and then access data stored in real-mode segment 0x40, even when
called in protected mode.  Microsoft unfortunately coddle these individuals,
and so must we if we want to run their code.

This change works around GPFs in some APM and PnP BIOS implementations.
