One needs even instructions to run vmware in vmware, so that was
to expect.

Bochs should do this, but dog-slow. Used qemu on a dom0 for myself, but
its probably still to slow for your uses as no kqemu-module can be used
to take shortcuts to run instructions directly on the cpu.

Thats exactly the scenario i use HVM on my private AMD-box here for.
Worked for every linux-distro so far, but apart from the linuxroad at
bsd, dragonfly etc. its stopping fast.
Running vmware-server on linux and a xen dom0 in a vmware-vm should work,
same for qemu/kqemu and xen in a qemu-vm.
I dislike that order and run xen on first layer.
You could also give KVM a try, maybe it plays better for linux-distros
on your intel-box.
Maybe it is also technically possible to shift the realmode-emulation into
the qemu-layer, have no technical background to say more on that.
