id_maddr iss a caddr_t, i.e. 32 bits on the i386...
it *should* be usable for any physical address, but
because of some hackery in isa.c, it'd be a bit
'interesting' to get it to work right...

I'm not sure how to get it to 'do the right thing' --
the code in isa.c should probably be changed to not clobber
the address if it's not in the ISA memory hole...

thoughts, charles?
