Yes.  The Cassiopeia has a Vr4102 or a Vr4111 depending on which
version you have.  There would be some code needed to get the cache
stuff working, but that should be relatively minor.

Good luck!

Actually the biggest problem that I've not been able to get past is
booting.  Most WinCE drivers run as user level processes, so I can't
steal the interrupt vectors from a driver.  Thus far, I've found that
the easiest way to go would be to burn my own ROMs...
