That would be me.

I do not get the stuttering, but I get a "warbling". This is a harsh,
buzzing distortion when I play MP3s. It starts randomly, and lasts 
about 10 secs.

I am using gugpnp17.

My card (A GUS PnP with 4 Megs of RAM) is not probed correctly. Only 
1024k of memory is reported at bootup:
