Sorry; still not possible.  However, see below for alternatives...

Win4Lin officially support running inside a Xen VM, I believe.  Their product 
is a modified version of Qemu, which you could just run inside a Xen VM 
directly.  I've occasionally toyed with the idea of trying to make this sort 
of setup a bit easier to configure...  maybe I should revisit this and see 
how feasible it would be.

Kqemu will not work in a paravirt domU for the same reasons that VMware won't 
(need to run in ring0).

Dave: Just a question. What use is a unicyle with no seat?  And no pedals!
Mark: To answer a question with a question: What use is a skateboard?
Dave: Skateboards have wheels.
Mark: My wheel has a wheel!
