The only other option I can think of, and again I have not tested it
personally, as I prefer the perceived reliability of a 4-port hardware
solution, is the Florz patch to bristuff:

I cannot get to the usual URL, but via google:

you can view the cached page.

This allows you to use interrupts from a single card as the trigger
for all cards in the system, reducing the resultant load to a
manageable level.

Best of luck.
