There is one in the sparc port. It should need very little tweaking.

Ditto. This code will need a bit more tweaking.

> drivers for xy and such

There are no drivers for any of the se/si/sc/sm/xy/xd cards. I've seen
free chunks for at least some, and the non-DMA 5380 driver could
probably be modified to handle the se/si/sc quite easily.  There is an
xy driver in the Sprite distribution (translation: write a new
completely new driver while looking at the Sprite code over your
shoulder.)
