Hmm. I'm not seeing any change.  I removed the sio2 and sio3 entries
and eliminated the other "unknowns", but pci0 is still not getting
found.

Did it, no pcm0 (or even pcm*) in dmesg or /dev.  sndstat tells me the
following:

# cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:

And nothing else.

The bios setting doesn't really give any options with PNP stuff.  I
though there would be a way to turn off the sound card, but I'm not
finding it.

I'm pretty sure it's PCI - it's onboard, so there's not much hope of
pulling it out to read it.

Well, not really, but that's probably more a reflection on me than you
:)  I sincerely appreciate your input, but I think this has just gone
past my pain threshold, which gets lower with each passing day - I
ordered a new Dell Shortly after posting the request, and it should be
coming in about 10 days now <happydance!>.  This system will probably
be retired for awhile until I can get the space to make use of it some
other way.

Thanks again Bob.
