Yep, unless the module provides a way to set it up (as said in last mail).

First of all I doubt we should build into kernel any drivers creating:

240-254 char    LOCAL/EXPERIMENTAL USE
240-254 block   LOCAL/EXPERIMENTAL USE
		Allocated for local/experimental use.  For devices not
		assigned official numbers, these ranges should be
		used in order to avoid conflicting with future assignments.

this way allowing system administrator to take care in any way (either
some script as you proposed or simply by strict loading order or sth).
