Here's what I found tonight, using the tape images from:

http://www.siliconsamsara.org/tapeimages/sun2/sunos-4.0.3/

tape1/09 is a .tar, containing sun2.bb and boot.sun2.  sun2.bb is
suitable for a single argument to NetBSD's ndbootd.  boot.sun2
should be placed in /tftpboot, with a 09ABCDEF.SUN2 symlink pointing
to it, where 09ABCDEF is the hex of your client's IP address.  In 
addition to ndbootd, configure and start rarpd, inetd(tftpd), 
rpc.bootparamd, and the NFS server as you would for a sun3 SunOS netboot.

Now extract tape1/05 as a raw binary, and install it in the diskless root 
under the name vmunix.

With all of that, you should see something like this on your 2/120 after 
you give "b ec()" (for 3Com Ethernet) or "b ie()" (for Intel Ethernet):

  Boot: ec(0,0,0)vmunix 
  Using IP Address 10.0.0.11 = A00000B.
  Booting from tftp server at 10.0.0.10 = A00000A.
  Downloaded 120936 bytes from tftp server.
  Using IP Address 10.0.0.11 = 0A00000B
  hostname: still-remains.home
  Boot: null domain name returned by bootparam server
  server name 'the-gates-of-delirium'
  root pathname '/data/export/sun2-elf-root'
  root on the-gates-of-delirium:/data/export/sun2-elf-root fstype nfs
  Boot: vmunix
  Size: 520864+90768+140016 bytes
  Boot: 

I dunno why it dumps me back at this Boot: prompt.  One guess is that
I'm booting the wrong kernel, and the right kernel loads at a different
address that this booter is then willing to transfer to.

What's the last thing you see before the hang?

Ya.  For one, the P2 memory bus needs to be properly terminated.  See:
