Yes, that should be possible. I have not tried it but it should work.
Just don't add the "planetcore" repository to the apt configuration. One
caveat is that for realtime schedulling access as a normal non-root user
you will need to either install the Planet CCRMA version of "pam" (part
of planetcore, pam-0.79-9.6.2.rhfc4.ccrma), or
edit /etc/security/limits.conf to give everyone (or a group) access to
realtime priority. The relevant part of Planet CCRMA's configuration is:

*               -       rtprio          99
*               -       nice            -10
*               -       memlock         4000000

What hardware do you have? It may be too new for proper support by the
linux kernel and that's why you are getting so much grief from it.
