Well...  It's been a long time since I zero'd my Seagate.  Other than that, 
yes.  If the detail in this mail doesn't help, I'll try zero'ing the Seagate 
first and then doing an install.  At minimum I've done this with NetBSD 
1.6.1 and it worked, but I can't say that's the case for 5 yet.

I re-zero'd the MTRON/ACARD combo (in my Adaptec SCSI controller BIOS, same 
as before).  Then I booted up NetBSD 5 (200902030000Z).  Here's the relevant 
portion of the dmesg:

Here's the sd0 (Seagate) disklabel.  (This drive had not been zero'd)
http://i39.tinypic.com/2uo57kl.jpg

Here's the first part of the MTRON/ACARD disklabel:

..and the second part (I did a ctrl-c because there's no 'more' on 
sysinst):
http://i39.tinypic.com/9r0en9.jpg

So even though I zero'd the drive, the disklabel is wacky.  When I did the 
zero'ing operation it completed super fast (a few seconds).  My assumption 
was because the device is a solid state drive.  But I can imagine it's 
possible that the ACARD's implementation of the SCSI zero'ing command is 
"cheating" and not fully overwriting the disk with zeros.
