Is this the audio on the Cyrix MediaGX (later National Semiconductor 
Geode GXm)?  I have access to hardware with that CPUs that I can test 
with if someone wants to write an ALSA driver. Er... though I'm not sure 
what VSA version the BIOS has.

I seem to recall that the Soundblaster 16 emulation provided by the VSA 
code worked fine so perhaps this can be dropped entirely.  I've not 
touched a MediaGX based board in many years so I may be remembering 
incorrectly.  The Soundblaster 16 emulation does work fine on AMD Geode 
GX1 boards.
