Well, it's mostly intended for distros so that they can enable the
option and detect places where they assume consecutive minors as
otherwise most of those will go unnoticed until some user finally tries
to use more than 16 partitions. As most distros are broken at the
moment, I'm more inclined to keep the debug option and planning on
enabling it during the next devel cycle of openSUSE and ask RH and other
distros to do the same. It adds ifdefs to ide-disk and sd, which isn't
too much. I think it would be good to keep it until at least distros
break out of the consecutive or fixed device number assumption.

Thanks.
