Did you start jack before? If you are using the Planet CCRMA kernels (or
another kernel with capabilities enabled) then you should be able to do
something like this:

jackstart -R -d alsa -d hw -r 44100

(or 48000, that will start jack with the default of two buffers of 1024
frames each). That should start the jack server (you can also use the
qjackctl gui for that).

After jack is up and running try:
  pd -jack

These two modules:

> ac97_codec             17224   0 [i810_audio]
are part of OSS, not ALSA, so probably you still have your OSS
configuration in /etc/modules.conf in addition to your ALSA config.
Could you post your /etc/modules.conf?
