The problem is not activation, the problem is that the patches are 
making assumptions on the driver and the firmware that might work today 
but are IMHO just not sane.

I would have no problem with a clean patchset that adds a new machine 
type and doesn't touch code in "-M pc", but it looks like mst disagrees. 
 Ultimately, if a patchset is too hacky for upstream, you can include 
it in your downstream XenClient (and XenServer) QEMU branch.  It happens.
