I have issues with alsa and the 2.6.6* series, too.
In short:
  - under KDE, I have no sound if I boot a 2.6.6* kernel, and any 
application which is sound-related either gives no sound or hang 
completely (must be killed).
  - under Gnome (my default), all system sounds are distorted / changed, 
and I experiment ramdom and _very_ frequent lock ups and freezes.

All this goes away if I reboot wit the original 2.6.5 FC2 kernel.

Your problem might or might not be related to this:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=125887
(look there for a couple of references to earlier discussions on this 
topic in fedora-list)

There's something broken in the 2.6.6* kernels; it affects only a few 
particular hardware configurations (and in different ways). Maybe it's a 
bunch of different problems... who knows.

Up to now, I haven't found any clue, nor any advice on how to debug this 
in more detail.
