Yes, Debian based systems all use PAM.
Hmm, have you been able to establish whether Dapper supports the new RT
priority rlimit OOTB, and if not, where the problem is (glibc, PAM,
bash, etc)? It definitely seems like this should just work.
IMHO this is the biggest obstacle to getting low latency audio to work
by default. Even with a non-rt kernel this should produce good results
(5-10ms for 2.6.14+ according to my tests).
