deva-audiopci problems with ES1371 and ES5880 chips

I have three different cards with these chips and none are recognised by
deva-audiopci. I am using a ASUS P5A motherboard with a K6-II 450MHz
CPU, although I’m not sure that makes a difference.

I downloaded the also-qnx-0.5 sources, verified that the chips should be
recognised, and started adding fprintfs. So far I have gotten to the
point that it is failing to set up the AC97 codec mixer.

Has anybody had success with cards with vendor id 1274 and product ids
1371 or 5880? Anybody with suggestions for source code changes that I
could make? Anybody know where to find the documentation for these

Thanks -
