Hello,

I'm attaching a patch that we have applied to the qemu implementation
inside of the kvm package in Ubuntu.

This patch was ported from a very similar one applied to gtk-vnc.

I spoke with Anthony Liguori on IRC about it a bit, and he as a few
ideas as to how to handle the configure bits better for QEMU.
Hopefully the rest of this is useful to you as-is.

Thanks,
:-Dustin
