An interesting way to get around all of those:  set up a v86 process that
calls the BIOS routines for you.  It can be done, and I've seen it (not for
the card in question, however), although I don't recall enough to make any
claims about performance.

It probably requires some kernel help, however.

There's more than one way to skin a cat, remember!
