 I'm using patched mopd to boot ELF Linux images (both ELF32 and ELF64)  
straight over the network successfully for many years.  Both over Ethernet
and FDDI.  Patches are available at:  
'ftp://ftp.ds2.pg.gda.plftp/pub/macro/mopd/'.  They were only tested on a
Linux system, but I'd be happy to hear if they work for NetBSD (or any
other system); more even seeing patches in case something's wrong.  I can
help synchronizing the changes with your source as well.

$ mopchk vmlinux
Checking: vmlinux
ELF 64-bit LSB executable
Size of seg #00:    0025ff10 (+ 000000f0 fill)
Size of seg #01:    00067000 (+ 000515e8 fill)
Load Address:       80040000
Transfer Address:   802a4000
