I've had some trouble with that off and on, the symptom usually being 
garbled sound output, but I've been running 2.6.16 for a while now, 
and light sound usage seems to be Ok.  Alsa modules,

$ lsmod
waveartist             15936  1 
sound                  75744  2 waveartist
soundcore               7716  2 sound

Recently I've had another problem: the DEC/tulip port (eth0 on my 
setup) has started dropping link for ~1 second at a time under heavy 
usage, which I really notice when playing quake/etc (my netwinder is 
my firewall, I don't play quake on it).  I read on the FAQ that the 
link LED on the netwinder is inverted, but I can see the link go down 
on the switch side,

I've been running 2.6.16 since last October, and this only started 
happening a few weeks ago.  I've tried different cables, different 
ports on the switch, to no avail.

Even if I retire it as my firewall, its still a neat little machine to 
have around.  I might try and revive the video-input/output one of 
these days.
