I missed the part where I was supposed to change from using the 
bootblock.READMEback to the INSTALL document.  :-)

I should add that I'm willing to write a section of the INSTALL document
that explains how to do what I'm doing from SVR4, if that makes sense.
Then, at least, everybody could point to the INSTALL document and say
"read the docs."  :-)

In any event, using sd0*, either via -psd0* before the timeout in the
bootblock program, or at the point where there is a prompt for "root device>"
doesn't work.  Given that the partition is actually partition 5 in the RDB,
is the swap partition actually 'b' in NetBSD?  As I said, I can't explore
some of this until I have a working system.  I also tried sd0e for grins.
It also leads to a panic.  And is it actually sd0, considering the SCSI
device number is 6?  (FYI, there is also another SCSI disk at '5'.
It doesn't seem to matter whether or not it is turned on.)  There is also
a QIC tape drive at SCSI 4.  There is an Amiga multi-port serial card, and
a 2-port serial card plugged into the bus, along with an Amiga 2065 (?) 
ethernet card.

'-psd0*' leads to no prompt for root-device, and a display of "No suitable
root."  Entering 'sd0*' at the prompt leads to a system panic.

Here is the procedure that I followed.  The difference between the
configuration shown here and before is that partition 9 (BSD_Root) is now
set to the correct filesystem type.  Also, FYI, partition 9 doesn't show
up as one of the offered partitions at boot time, just in case that 
provides a clue.

Here is the current RDB info under SVR4:
