Oh I didn't realise you had more plans in this area :) Any idea when
you'll be able to work on the them? TBH as you probably already know,
even the patchset in its current form with the ISA bus encapsulation is
so much better than what is already there, so I'd prefer to merge it and
help you work through any problems later unless you feel particularly
strongly?
ATB,
