David, I guess everybody who makes serious audio work needs a kernel-rt
too, hard to imagine that some people really don't need a kernel-rt.

I'll test kernel

$ uname -a
Linux debian #1 SMP PREEMPT Tue Jun 7 01:40:05 CEST 2011 x86_64

Just PREEMPT? No RT? I don't know.

I once had a kernel PREEMPT and there were issues when I tried to use it
for audio. But perhaps the vanilla is ok.
