Run in fear.

Despite having a number which is just a wee bit higher than the
things supported by the existing Plan 9 NCR/LSI SCSI driver,
this is an utterly different beast, based on LSI's "Fusion"
architecture, which in theory simplifies things vastly for the
host over the old sequencer/script architecture, but all of the
simplification is balanced out by vast complexity additions in
other areas (addressing devices in terms of target and LUN is
obsolete, so there are two or three other ways that devices can
identify themselves, and a host is supposed to set up a mapping
from long identifiers to short ones for, and for some reason I
didn't get on first reading the host is supposed to use the same
mapping across reboots).

Also, I think that in addition to talking to disks over this
SCSI adaptor, you can also send network packets.
