> Georg, how do you know the OP wants to target embedded systems?

I don't know, it seems reasonable, though, to assume
embedded systems here because Minix 3 announcements
say it is being made suitable for small, embeddable systems:

 "MINIX 3  adds the new goal of being usable as a serious
  system on resource-limited and embedded computers and for
  applications requiring high reliability"  (minix3.org)

Thinking again, though, if I'd want to offload the
portability work to a non-Ada layer below an Ada
kernel, e.g. Xen etc. block drivers, the interesting
plan that Dmitry Kazakov has laid out might have a better
chance, as there is more time to concentrate on an OS
featuring a better API. (E.g. modules, not functions).

And, you're right, results might be usable earlier,
provided there is more hardware supporting Xen drivers
than original drivers.

(Incidentally, it is possible to run Minix 3 on VMWare
Workstation.  I needed to select to a version 5
virtual machine, though.)
