The 154/0 is the major/minor numbers, so

	critter phk> cd /sys/conf
	critter phk> grep 154 majors 
	154     asr             Adaptec SCSI RAID <msmith@freebsd.org>

The asr driver actually contains some very creative but equally
bogus code in the function asr_drvinit().  I think you can
remove that function entirely with no ill effects, but have no
hardware I can test this on.

Never attribute to malice what can adequately be explained by incompetence.
