All I can suggest is going through the ICH sound docs.  Intel write both 
register descriptions and programmers guide for their h/w.  You might also 
look at the ALSA driver.  I believe the speed problem most likely lies in the 
AC97 resets.

I know I promised to look into this, but I've been struck by a shortage of 
time lately and don't see the situation improving in the near future.  I'm 
very close to calling it a day with the commit bit.
