I always considered that wierd, wouldnt a kqemu type thing be the way to go considering that they are am chips *i belive thay are in the same family)
thinking this over, qemu would be the way to go for somthing like this as it has proven to me at least to be flexible enog to do some wierd things (driver development for hardware that dosent exsist (look up the hardware ROT3 "lovey rusty" crpyto pci card) and the ability to allom non native bainaries to run (eg run arm binaries on a x86)
