Ah - now I get it. I think I'd settle for two instances of the "common
driver". Even if part of the source is shared but results in two
different object modules, the sharing is a good thing when you
consider maintenance of the driver.
But before the ISA if_ed can be used for example with GoldenGateII in
an Amiga, the interrupt priority issues need to be addressed. I
haven't had time to upgrade my sources (and won't have before summer)
so I don't know whether something has been done in this area. Niklas
has committed his interrupt priority remapping code to OpenBSD. What
