I've applied a workaround to device-mapper cvs today that I hope
will handle this.

For old kernels, libdevmapper detects if a device number is being 
supplied to an ioctl without a name or uuid, and if so, issues 
extra ioctls to translate the device number into a name first.
(Inefficient, but it should work.)
