if i understand this patch and the gfx_passthrough parameter right, you don't 
need this patch for this scenario: 
with gfx_passthrough=0 this patch does not what its intended to do, i.e. 
"declare" itself as the primary gpu within the DomU which would mean you could 
also see early boot messages and windows start screen on the monitor of the 
passed-through gpu (a feature i not really need).
