I have attempted something similiar in OpenBSD (I want a number of switches and routers accessible via console), with 4.2. I have had problems.

I've been able to get the four-port serial card (mos 9835 like yours if I'm not mistaken) recognized and I get a grand total of ONE of those four ports to work.
I don't know if the system is finding confusion because they all answer on the same IRQ, or what.

I am going to test out the same card on 4.3 and 4.4 (when it comes out), so I'll try to remember to post back here when I do my testing.

Here's the portion of my OBSD 4.2 dmesg- it sees them all, so why can I only hit the first one!?!?!
