OK, that makes sense.  Legacy interrupts (<16) will be automatically set
up, and that would be enough to get the system into a semi-working
state, but beyond that setup would fail and devices requiring them would
not work.

It would probably be a good idea to put a nice big clear warning message
up to alert people to the problem...
