Thinking again about that, it maybe isn't all *that* hard. Bochs already
does know about the concept of shared DRAM and ROM BIOSes etc. Maybe
it's really just enough to hack it's memory class (yup, it's written in
C++) to not back the memory by RAM or on-disk storage, but to redirect
all accesses to physical RAM.
The same is to be done with I/O ports too, of course... For complex card
(SCSI RAID host adaptors), you may need to service interrupts, too:-(
