AFAIK PREEMPT_DESKTOP was introduced early in the 2.6 series. 
If it was enough, we didn't discuss about low latency 
anymore, but we do ;-) .

For audio work, a latency of more than zero milliseconds is 
still too much.

I really hope to get a latency of about 4msecs. Currently, my 
USB card runs at 16msecs and you can feel that. Play a 
softsynth percussively...

ret_rtlimits is well documented by a README and a manpage.
