> The easiest place to add this would be as a falg bit in d_flags;

sys/conf.h is suitable place:

/*
 * Types for d_type.
 */
#define D_TAPE  1
#define D_DISK  2
#define D_TTY   3

#define D_TYPEMASK	0xffff	/* we can add four more types. */

#define	D_UNCLUSTER	0x10000	/* disable clustering I/O */


(`d_flags' is also used in disklabel structure.)
The d_flags member of bdevsw structure is referenced from
kern/kern_conf.c and miscfs/specfs/spec_vnops.c in 3.0-current.
