Just thought I'd give it a try and to my surprise the original CD boots perfectly. 
I'm using qemu-kvm 0.14.0 on 64-bit Linux.
I wish I knew where my CD was. Never got it to work on my laptop, and have since lost track of it.

This could be an interesting way to work on drivers for new hardware items, using the QNX Rbus to link in verilog RTL code for peripherals. ie. play with drivers before putting the peripheral into a Minimig FPGA. I'm not sure that this rbus thing is available for general use by RTL people, but it's been interesting reading.
Anyone else got Amithlon working in Virtualbox or Vmware?
