Yes, I should have mentioned that both of those are also ok with me.

Ooh, haven't looked for those.

The vanilla kernel that I patched is 2.6.18.  The default ubuntu
kernel is 2.6.15.  I'm not sure what you mean by -rtN?  I run pd with
-rt, should I be adding an integer, or are you talking about a kernel
compilation option?  I turned on full pre-emption, of course.
