Correct, if you run uname -a you'll see that there's no PREEMPT for the
output. I'm using Debian testing + a little bit of Debian stable, but
build the 2.6.39 myself by using the config of a self build
2.6.33.9-rt31.
Members of this list explained the reason why the default Debian kernel
isn't PREEMPT-rt-emulating.
If needed I can send you a script to build the kernel.
