Unable to retrieve any such information.
Trying to boot either kernel or miniroot for installation, kernel
reports presence of hard disk (Seagate 1.3gb/EIDE) and CD-ROM
(Mitsumi 4 speed/IDE), then informs of 7 other SCSI devices reporting
nonsensical geometry (mode sense 4).

Then reports "10 views configured", and halts. Caps-lock responds
by lighting up upon press, so maybe it's not completely dead.

(System is A1200 68030/MMU/25MHz, 4MB RAM, no FPU, on a GVP card)
Simply boot the miniroot from the swap fs, or boot the kernel with loadbsd.

From the NetBSD-1.4 Install document, e.g. 

NetBSD/amiga System Requirements and Supported Devices 
The minimal configuration requires 6M of RAM (not including CHIPMEM!) 
and about 75M of disk space.  

So you should expect that it doesn't currently work on your 4 MB machine. 

This is a known, but not analyzed problem. As netBSD/Amiga feels much 
faster with 8 MB than 6 MB; MUCH faster with 12 MB than with 8 MB, and 
even MUCH faster with 16 MB than with 12 MB, this is not the most 
urgent bug on our list...

 Rob, Petri:

 there is a reason I didn't close the PR.

 NetBSD/Amiga not booting at all on a <6MB machine (for todays kernel sizes
 for <8MB) is the result of a bug, or more probable of the general misdesign,
 in the pmap module. Basically, pmap needs to be rewritten, and this won't
 happen fast, but when it is rewritten, a 4 MB amiga should be able to
 startup a small enough kernel and, while not to run it, at least to crawl it.

 Thats the reason that PR is still suspended and not closed.
