Masks might work for DRQ's and IRQ's, which are small integers anyway, but if
something needs multiple memory spaces then you're in trouble. I don't know
that anything would actually want to do this (and if it did, it sounds pretty
icky 8-), but mycroft's suggestion would let you do this, whereas the masks
would make it difficult

Would it be easier to use a "mask" instead? i.e.:
sb0 at isa? port 0x220 irq 1 drqs 0x22 # 1,5
gus0 at isa? port 0x300 irq 1 drqs 0xA0 # 5,7

Note, I'm not objecting; just offering another idea.
Use it or not as you like.
