certainly running vmware on a PV DomU is absurd, since it doesn't have
access to ring0, not even in kernelspace.

but in Dom0... any userspace app should run, and 'most' kernel modules
should also. Qemu runs as a pure userspace app, but kqemu has
problems... maybe solved now that it's open source?

it would be very nice of VMWare if it could run in a 'pure userspace'
mode... but i guess it's too different architecture and too few little
market for such a feature.
