I've noticed that device drivers listed in arch/xen/conf/files.xen

[141 -1 xenevt]
[142 142 xbd]
[143 -1 xencons]
I think this lists all the known major numbers for the $MACHINE, I don't think
it means that the driver is actually loaded.
... and a PVHVM guest can use the GENERIC kernel, but will want the Xen
devices too.
Thanks to all for the info.
Manuel is correct - I actually checked the build object directory and
there are no *.o files related to the xen devices.
