Right now I don't think there is any support for ISA pass-through, but
it could probably be done, even if it sounds pretty scary. There's a lot
of risk with ISA cards, they can easily take down the whole system, and
if it does DMA you are probably out of luck.
You might find someone on the list willing to do the work on a contract,
but I will let interested parties reply to you directly. I cannot do it.
Cheers,
