i will certainly do that. Dave and i have mobos from ECS, Dave's using 
the RealTek ALC100/P AC'97 CODEC chip in his Via south bridge, and mine 
using a CMI9739/6CH AC'97 CODEC in an Sis south bridge. i browsed around 
in the 2.6.10 changelog and it looks like there's a fair amount of work 
being done in the [ALSA] area wrt to AC'97 (both of our codec chips 
mentioned in several separate entries).

i will certainly let the ALSA folks know what happened and how i fixed 
it (not really a fix, more config).
