Theoretically it may be possible to reverse engineer a good proportion of=20 ARMv6 from other sources (eg. gcc).

I don't think that's particularly helpful or practical suggestion. Better would be to lobby ARM to allow open source emulators.=20 "I'd like to use ARM hardware for , but qemu doesn't support=20 ARMv7 so I'm thinking of using PowerPC instead" is a particularly good=20 argument ;-) Paul
