Initially I can, on the first boot it drops into single user
mode.  
After mounting /, no.

On first boot...  /dev/rsd0a:  character special (13/0). 
After 
mounting /, and booting with an install kernel, I get... 
use one of:  
fd0[a-h] sd0[a-h] se0 ddb halt reboot

NetBSD-4.0_RC5.  I used the MacOS mkfs utility.

Initially, yes.  After mounting /, no.

None of the NetBSD3.x kernels have booted on my machine. 
They all stop 
at... panic:  no init.

Uh huh. This sounds fairly similar to a recently fixed issue
with old
filesystems created by the MacOS mkfs tool.

Can you please send-pr the issue? There's a web form at
<http://www.netbsd.org/cgi-bin/sendpr.cgi?gndb=netbsd>
;.

If you can boot into an install kernel and drop to a shell
prompt,
something like

fsck_ffs -c2 /dev/rsd0a

should be able to upgrade the filesystem to something that
makes sense to
NetBSD 4. Otherwise... you'd need to set up the disk from
scratch with
sysinst.

Could you post exact whole messages you saw?
I don't see any programs which could show
"magic numbers do not match" strings.
("BAD MAGIC NUMBER" of fsck_ffs?)

Fix for "no init" problem was pulled up to
netbsd-3 branch
after 3.1 release so you could try daily snapshot of
netbsd-3 branch.
