Major numbers are now dynamically assigned.  The shims for allowing
drivers to choose a static major number were removed a few months ago.
There is no work-around for this; just don't include the field anymore
in 6-current sources.  If there is something that thinks it needs
explicit knowledge of major numbers, let me know and we can discuss how
to fix it.
