Thanks Daniel for this :) 
this works fine on my Thinkpad z60m (hdac = '82801FB/FR/FW/FRW Intel High
DefiNition Audio Controller' ), but :

 - volume is *very* low - it is barely discernible from background noise.
mixer reported initially a value of 77%, which i pushed to 100 with no change.
dev.acpi_ibm.0.volume was 14 (max) , so the speaker beeping was very loud, but
pcm wasn't at all.

- lack of recording (mic) / input - not sure if this patch was added to your
tar ball

Andrea's original package from darkircop.org doens't show the mic either, but
the sound volume works fine.

I'll test Andrea's -rec.tgz now.

Please let me know if you want any debug information :)

Cheers,
