I can see your point, but if every workaround were present, the config
file would get unwieldy.

Also, see cardbus(4) and pcmcia(4).   Similar issues are documented
(based on Thinkpad 600 and 600E!).

Would it make sense to have a known set of overrides for

RBUS_IO_BASE and PCIC_ISA_ALLOC_IOBASE? Even if it is keyed by something like machdep.dmi.system-{vendor,product,version} or similar, it would be nice to be able to get it right automatically in a few more cases.

Alternatively is it possible to map it and poke it to see if its working, then switch to a fallback address if not?
