Here are few register dumps I took with the Emu10k1 driver modified to 
do no writes and an added proc entry to dump the registers.

The first is the state the first time I loaded it (regs-before.txt). The 
second is the state after loading/unloading the OSS eval module. The 
third is after playing an MP3 with the OSS module.

I still had no luck in getting anything playing, so any insights are 
appreciated.
