Yeah, that's really annoying.  I can't change the kernel without also
having a flag day to update libxc.  I guess we could make sure all the
stable Xen branches get a libxc fix backported to them, but I wonder if
it would break other toolstacks?

But if we don't make any kernel changes then libxc will muddle on even
if udev stops handling the device name properly?
