The hard work in an OS port is porting all the device drivers to a new
OS: serial port, ethernet and so on. If you choose one of the major
platforms supported by QEMU (for example, the ARM versatile range) you
will find example code to work from in Linux, in NetBSD and so on).

I found QEMU to be very solid as a platform. You can treat it as it if
were real hardware :)

That's a big question! :) I suggest you start studying the structure
of Minix, and the sections that differ from processor to processor.
Minix only works on x86 processors :-( but http://www.minix3.org says
"Ports to ARM and PowerPC are underway." so your first move is to
check with whoever is doing these ports, to know how far they have
progressed. I am sure they will be very pleased to receive your help
and to work with you!
