da1 at ahc0 bus 0 target 2 lun 0
da1: <CONNER CFP4207S  4.28GB 2847> Fixed Direct Access SCSI-2 device 
da1: 3.300MB/s transfers, Tagged Queueing Enabled
da1: 4096MB (8388608 512 byte sectors: 64H 32S/T 4096C)

I've checked through all my /var/log/messages*; there are no 'tagged
openings' messages at all.  This was with a -CURRENT kernel about 2
