I'm not sure that is even true any more.  No recent data, but I tested jackd
extensively in about the 2.6.7 to 2.6.11 time-frame, and found those vanilla
2.6 kernels quite competitive with RT-patched 2.4 ones, at least on the
machines I was running at the time (all uniprocessors).

The very early 2.6.x kernels were another story.  :-)
