It's true. The easiest alternative IMO is to use set_rtlimits. A quick
explanation is at http://tapas.affenbande.org/?page_id=22

Basically you download and install this:
http://www.physics.adelaide.edu.au/~jwoithe/set_rtlimits-1.1.0.tgz
then add something like this to /etc/set_rtlimits.conf: 

@audio  /usr/bin/jackd  -1 90 

assuming you have a user group "audio" and start jackd like: 

$ set_rtlimits -r /usr/bin/jackd --realtime -d alsa -d hw:0

Alternatively you can use a patched PAM-module, but that is a bit more
work, if your distribution doesn't ship it.

Ciao
