If this is done, you'll have to be sure that any non-0 functions assigned  
to guests (which will appear as function 0 to the guest!) does not appear  
to have VPD and block access to those resources. That seems kind of messy,  
but should work. One hopes that no guest drivers are hard-wired to assume  
VPD presence based on the device type.
