The card is a generic PCI card, it's labeled "Mercury" on the box, and has a
Sun chip on it. I see it's detected as a Dolphin card, and I _assume_ that
is correct.

The weirdness with it being COM5 and COM6 had to do with weirdness in my
kernel conf file.

I suspect the problem is that I need to pass certain flags in the kernel
conf, but I don't know which ones.

The good news is, after having spent a couple of days fighting this, and
getting to the point I was locking up the computer with it, it dawned on me
that I had started out there. So I went back and found out that I probably
had the IO address for the on-board CO<1 chip wrong originally. Now it seems
to be working, which will let me deploy the machine!

Thanks for your help on this. I still plan on putting the PCI card in
another machine and trying to get it to work, but that may take a while to
get to.
