Hmm.. How about if we define new targets for dprintf?

Like you load module debug_vmware/qemu/serial/or something common. Then
it would provide new environment variable where you can set target of
dprintf. Though dprintf would then need to provide hook to allow
redirecting of those, but that should not be big deal.
