Lots of BIOSes (a million monkeys bashing on typewriters will write
something that passes some BIOS vendor QA in about 2 seconds) illegally
assume that 0040: points at the BIOS data segment 0040 when making APM32

PnPBIOS has to rewrite segments as it goes for data passing. It doesnt
really matter where you stuff them though.
