If you know what you are doing you can manually remove the check for

This is exactly equivalent to adding "xen_emul_unplug=unnecessary" to
the kernel command line, isn't it?
Conversely if you want to always force emulated devices (i.e. disable
any attempt to unplug) then "xen_emul_unplug=never" will do what you
want.
OK, I am confused. What I want do is is bring the PV devices up as
/dev/xvda not /dev/sda. I don't much care whether or not it attempts to
unplug the emulated devices, as I can cope with or without the additional
presence of the emulated devices.
IE I want it to work just like it used to work with unmodified_drivers.
Is there a command line option for that? Or if not, I am happy
to try and work on a patch.
