Tricky.

If you're a service ROM you're in the machine early enough to intercept and
parse the start up banner from a table of known banners.

If you're not a service ROM if you probe at 0x00000000 and 0x00010000 for an
alias that'd tell you if it was a 16 bit memory map or more, but beyond that
it'd be hunting for strings in the ROM area I think.

Both messy and tedious,
