I found a problem with that streamer on raid controller Dell Perc-4Di.
It seems that booting with FreeBSD 6.0 install cd, device sa0 exist:
sa0 at amr0 bus 1 target 6 lun 0
sa0:<SEAGATE DAT DAT72-052 A060> Removable Sequential Access SCSI-3 device
Serial Number ......
but booting with FreeBSD 6.1 install cd, device sa0 doesn't exist,
verbose dmesg doesn't show any such device.
Full installation of 6.1 and cvsup, build, install world + kernel
(either GENERIC or SMP) doesn't help at all.

It seems that somewhere between 6.0R and 6.1R something bad
happens to kernel or FreeBSD amr driver scsi subsystem.
