This is kqemu you are talking about, right?

There is an OpenSource initiative, too.  Although GPLed.
http://savannah.nongnu.org/projects/qvm86/
(haven't used it, just learned about its existence)

I understand that these modules run guest code in the native host
environment (with some protection mechanisms applied to still have the
guest supervised).  While qemu _really_ emulates the hardware, including
the CPU.  That's why you can have qemu emulate PowerPC, SPARC and ARM
hardware on an ia32 PC.  I guess the speedup from the above modules only
applies when the guest and host are of the same type.
