 That seems impossible in the real world. I don't think it's possible to
detect physical connectors on a PCB for any bus -- I've even seen boards
with soldering spots for bus connectors but no connectors themselves.
Relying on reporting anything optional being done right by a BIOS is an
illusion -- even mandatory things are screwed in many PC BIOSes. For the
said boards firmware is likely identical as for ones with real connectors.

 Also the choice of devices to depend on CONFIG_ISASLOTS is tough? How do
you know which ones exist in an on-board configuration somewhere and which
ones do not?
