does this routine exist now, or when will it be in the trunk?
I couldn't find anything in the trunk.

does it work before dk_establish() has been called by the scsi
subsystem? it needs to work that early, since the sparc port does
bootpath calculations at that time (doing them later on would be an
extremely difficult change.)

does it tell me whether the device is an sd, st, cd, or otherwise?
I'm not sure if I need this information, but it might be nice.
