which is hardly nice. This patch fixes this by having each
PV driver check for:
 - if running in PV, then it is fine to execute (as that is their
   native environment).
 - if running in HVM, check if user wanted 'xen_emul_unplug=never',
   in which case bail out and don't load PV drivers.
 - if running in HVM, and if PCI device 5853:0001 (xen_platform_pci)
   does not exist, then bail out and not load PV drivers.

P.S.
Ian Campbell suggested getting rid of 'xen_platform_pci_unplug'
but unfortunatly the xen-blkfront driver is using it, so we
cannot do it.

Thank you. I need to do some extra changes to the other subsystems but
for the fb/kbd itshould be still throught the same function as this
patch has exposed. I will repost it and include your Ack if you are OK
with that?

Sure.
