Well, I'm still not getting any further.  I pulled the SB Live! card out 
and enabled the on-board sound in the BIOS, to see if doing a kldload 
snd_driver would recognize *that*.  It doesn't. 

The on-board sound shows up like this in pciconf -l -v:
    none12 at pci0:16:1:       class=0x040300 card=0x2a3e103c 
chip=0x026c10de rev=0xa2 hdr=0x00
        vendor   = 'NVIDIA Corporation'
        class    = multimedia

kldload snd_driver followed by cat /dev/sndstat yields:
    FreeBSD Audio Driver (newpcm)
    Installed devices:

just like before. :(
---------------------------
Information I can glean from looking at the SoundBlaster card:
    On the board:
        Sound Blaster Live! 24-bit
        Model: SB0410
    On the chips:
       Creative CA0106-DAT LF (c) Creative Tech '02 C0524 KD692
       Cirrus Logic CS4382-KQZ WAEXAR0452
       WM WM8775SEDS 4AAADOG

Everything else on there seems to be simple resistors, caps, and maybe a 
mosfet or three.

Changing emu10k1.c so that the definition of EMU10K1_PCI_ID matches what 
pciconf -l -v found gets the module to recognize that there's a card 
there, and then it pukes on the ac97 stuff (which confuses me since this 
card claims to be ac97 compliant and the Cirrus chips is there ...)
   pcm0: <Creative EMU10K1> port 0xcf00-0xcf1f irq 18 at device 10.0 on 
pci3
   pcm0: AC97 reset timed out.
   pcm0: ac97 codec invalid or not present (id == 0)
   device_attach: pcm0 attach returned 6

Looking through sound/pcm/ac97.c I can see that the reset() function is 
failing, and the id = line in the ac97_initmixer() function isn't 
recognizing the chip on the board.

I got a SoundBlaster Live! because it was listed as a known working 
piece of hardware.  Apparently this is a newer version of the board that 
isn't supported yet.  Getting it to work is becoming a PITA beyond what 
I have the time and willpower to put in right now.

Is there a piece of sound hardware I can just run down to CompUSA and 
buy, that I can drop in here and get this thing working with *today*?
