I'm using it on two machines in the lab.  One has two identical
Quantum Fireballs, and the other has a Fireball and a Western Digital
Caveat (ahem Caviar).  On each machine most of the partitions are
striped, but at least one is not.  It works fine.

You need to compile a kernel with bultiple device/RAID0 support and
you need to install the debian mdutils package.  Then read the stuff
in /usr/doc/mdutils.  That's it.  The md package doesn't care if the
drives are the same type, or even on the same kind of bus.  That's the
advantage to a software implementation.  Granted I would expect
performance to be best when you have 2 identical drives on the same
kind of bus...
