Hi Vaughan.  Just a thought, but did you get the following 2 packages, the low 
latency kernel ones.
apt-get update
apt-get install planetccrma-core
apt-get install planetccrma-core-edge

The first one comes with extra packages. "rtirq" "rtload" (for realtime), and 
a couple of Alsa packages IIRC.

These are for the single processor setup, add "-smp" without the quotes to 
both packages if you are using a dual processor.  Nigel.
