After setting up these packages in my jaunty chroot ( from
http://talk.maemo.org/showthread.php?t=27735 ), and much thrashing
(log lost), I managed to get pcm.c working both in jaunty and in
diablo:

  libpci3 (1:3.0.0-4ubuntu8) ...
  lsof (4.78.dfsg.1-4) ...
  pciutils (1:3.0.0-4ubuntu8) ...
  linux-sound-base (1.0.18.dfsg-1ubuntu8) ...
  alsa-base (1.0.18.dfsg-1ubuntu8) ...
  alsa-utils (1.0.18-1ubuntu11) ...

I'm not exactly sure if that's what fixed it or if it was something I
did via diablo.
So ... based on this new evidence, I don't think it's the kernel or the driver.
