This is exactly what's happening now. BOCHS BIOS adds UUID to SMBIOS
table. You can see UUID that you provide on command line by running
"dmidecode | grep UUID" in a Linux guest. If you worry that UUID
backdoor is accessible from a guest then we can make it one shot
i.e disable it after first query.

OK. What about applying these patches (I can resend them if needed):
http://lists.gnu.org/archive/html/qemu-devel/2008-06/msg00443.html
http://lists.gnu.org/archive/html/qemu-devel/2008-06/msg00444.html
http://lists.gnu.org/archive/html/qemu-devel/2008-06/msg00446.html
They add -uuid command line option, but don't plumb UUID into the BIOS.
We will figure out later how to pass it there.
