I would not suggest using SCBPAGING in the NetBSD version of the driver.
It only became truly robust when I revamped the driver for CAM (not SCAM)
and both tagged queuing and scb paging are always enabled in the current
FreeBSD driver.

CAM = Common Access Method
SCAM = SCSI Configured Auto-Magically.
