"rtload won't" means rtload won't start? What happens if you try to stop
and then start it explicitly (as root)?

  /etc/rc.d/init.d/rtload stop
  /etc/rc.d/init.d/rtload start

Or try to load the module explicitly: /sbin/modprobe realtime any=1

The module should be found, it is part of the kernel I shipped. If it is
not there double check you are indeed booting into the new kernel (uname

Hmmm, sounds like an alsa problem.

You need to install the alsa jack plugin (I have never tried to use it
so I don't know if it will work at all):

  apt-get install alsa-lib-jack-plugin

No, it is not usual, please don't say "yes" to the prompt till we find
out why this is happening.

There is some conflict between the packages you have installed and the
Planet CCRMA ones that apt cannot really resolve (without messing up
your machine!). 

What are the packages it wants to install? Try installing each one of
them explicitly to see what is the effect. We have to track which
dependency is currently triggering this problem.

Interesting, I'm getting a dual opteron tyan board for the new Planet
CCRMA build server. Still waiting for the processors to get here....
