  I'm sorry to bug you again. I know it's not
your patch but I read in
 the lau mailinglist that you have it working. Hope you can help a
 nOOb like me. 
Actually, I don't.  I've been too busy with other projects.  I still
run the realtime-lsm here.  It's so easy...  ;-)

Jody recommended asking these questions on linux-audio-users (copied
here).  You are certainly not the only one having trouble configuring
rlimits.

  Now the question about rlimits.
 I applied the patch and modified /etc/security/limits.conf according.
 My user acount also belongs to the audio group, but I have no idea how to 
 start e. g. jackd in realtime mode. I looked several times at the wiki 
 and in the lau mailinglist but I havn't found a hint. 
Did you apply the PAM patch?

...
  Can you tell me how to start a app as user with the
rlimits patch?
 Neither 'jackd -R ...' nor 'nice -n -10 jackd ..' do work. 
jackd -Rv -dalsa

If that does not work, then things are still not configured correctly.
The -v option is for debug output.  Once it's working you can leave
that off.
