First we'd need to implement privileged CPU modes, system control coprocessor, 
and maybe MMU...

I'm a toolchain developer, not a kernel hacker, so I'm mostly interested in 
user-mode emulation. Full system emulation is probably not gonna happen 
unless I get really bored, or someone else does it ;)

Armv6 (ie arm11 series cores) and VFP coprocessor are higher priority for me.
