I am desperately looking for a mail from Philippe where he explained it,
but can not find it back. Maybe he can give some explanations.

Yes.

The newer versions should work, though I would recommend to wait for the
next release which should happen in the next few days.
Also note that I guess you are using Xenomai on the bifferboard, since I
also guess the processor on this board does not have a tsc, it will be
emulated using the PIT, which is slow, so, unless you can provide
another hardware timer with a lower latency, which will work starting
with the I-pipe core for Linux 3.4, you should turn off
CONFIG_XENO_OPT_STATS to improve latencies.
