I got it to work.

My problem was simple in hindsight.

I had booted DOS first, aborted a lengthy configuration of my
sound card, tested the serial ports, then "warm-booted" my
machine ( ctrl-alt-del ). I then brought up FreeBSD. 

By this process, my sound card was partially configured and
the software programmable IRQ's ended up conflicting with
other cards installed in my system ( including the serial
ports ).

I can duplicate this behavior at any time. 

The solutions are simple ..

A) Never abort the configuration of my sound card during DOS boot.

B) Power down the system before booting unix.

C) Boot straight into unix.

Options (A) and (C) sound fine with me.

Thanks for the feedback.
