Without pnp, I don't think you can enumerate the ISA bus. Hence I chose
"isa:" in the hope that udev would "just work" if isapnp created the
modalias under /sys/bus/isa...

But Kay says there's a pnp bus (who knew?).  I don't know what he means
by unfixable aliases tho, since it's all in the kernel source so we can
change it at any time?

Thanks,
Rusty.
