SubjectRe: 2.4.19 -- ac97_codec failure ALi 5451

I've downloaded the latest driver and am running 2.4.20 (yea!) -- the trident.c here
is actually more recent than 2.5.55. It now loads fast and with no protest from
ac97_codec, which has a new ID (ADS114). However, there's still not a peep (I try
cat test.mp3 > /dev/dsp) -- and when KDE Control Center tries to restart the arts
sound server, it alarmingly fails on "CPU overload" or just freezes the whole
system. Is there anything I can do to get more information about what is not
happening?

Cheers,
Peter
