Dear folks,
I have two LSI raid cards, one of which (SCSI 320-I) supports
64-bit DMA when 4GB+ of DDR is present and another which
does not (SATA 150-D) . Consquently I've disabled 64-bit
addressing for amr devices.
I would like to disable 64-bit addressing for the SATA card, but
permit it for the SCSI card. Is this possible?

# grep amr /boot/loader.conf
hw.amr.force_sg32=1

# grep "amr.: <LSILogic" /var/log/dmesg.yesterday
