In the interim you could try set_rtlimit: http://www.physics.adelaide.edu.au/~jwoithe/set_rtlimits-1.1.0.tgz It allows you to access the enhanced rlimits (ie: RT scheduling and nice levels) under 2.6.12 kernel or later without needing to patch anything. In fact, even once PAM/etc are patched this might be preferred by some since it allows you to control the limits based on the program being run; so for example you can allow /usr/local/bin/ardour to run at realtime priority 50 while /usr/bin/yes (for example) can't.
