I cannot say for 2.6.24 but as of 2.6.25, one cannot use realtime-lsm any
more.
Earlier kernels, one had to compile the capabilities-lsm as a module:
CONFIG_SECURITY_CAPABILITIES=m
and then build realtime-lsm using m-a.
One can no longer do this, so are now "stuck" with the standard security
setup. All is not lost, however. Rlimits is the default functionalities so
place in /etc/security/limits.conf
# audio facilities:
@audio - rtprio 95
@audio - memlock 512000
@audio - nice -19
and this should do the trick.
As long as you are compiling the kernel, get Ingo Mulnar's rt patch.
