Having kicked myself for being so stupid, I now realise why the co-installers 
are not working as I expect... The InitSafeBootMode override in XENBUS is 
preventing FDO creation, hence there will be no child PDOs, hence no other 
driver's co-installer is ever going to run.
So, my plan is to simply prevent emulated device unplug in safe mode and remove 
the override from other drivers. The lack of unplug should cause PV devices to 
become inactive anyway, which achieves the desired effect.
