Topic: what is snd_soc_stmp3780_devb, and why can't I find it?

I am seeing this in the console messages as my CHB V1 boots:

Setting 0x800182d0: 0x33333333 -> 0x11111111 ok
Setting 0x800182e0: 0x00333333 -> 0x00111111 ok
[   21.240000] i2c /dev entries driver
FATAL: Module snd_soc_stmp3780_devb not found.
[   21.960000] Chumby timerx[2] driver version 3.0-Falconwing initializing (bunnie!
[   24.810000] input: stmp3xxx-rotdec as /devices/virtual/input/input2

So, what is snd_soc_smtp_3780_devb?  Why isn't it found?  I've been fuzting with slinging WiFi drivers in and out, and I don't recall if that message has been there from the beginning or if I b0rk3d something.  If somebody with a CHB could check their console messages for the same message, that would be helpful.

Also, I'd like to buy a clue about what it is...
