In the wake of a recent discussion about Xenomai 3, the requirement to

You may now find accurate information about which hardware Xenomai runs
on at those locations:
http://www.xenomai.org/index.php/Embedded_Device_Support
http://www.xenomai.org/index.php/Other_Hardware_Support
PS: using the latest stable Xenomai release is implied.

Why subjecting yourself to the pain of running a complex application in
kernel space? The difference between kernel and userland latencies on an
mpc836x should not be worth it.
