My setup was similar (except I simply renamed the bootloader to the MAC
address, taking care to make hex digits lowercase and .SYS uppercase, as
the doc warned). I used installation/netboot/boot from 6.1.3, and served
it from mopd running on Debian/sid.

The failure looked like:

-ESA0
  83 BOOT SYS


... looping over and over until I pressed the Break key.

Doesn't this sound like the relocation problem discussed earlier in this
thread?

I don't see anything in 6.1.3's release notes that addresses this issue,
so I guess even though this discussion started before the 6.1.3 release,
no code coming out of this discussion actually made it into the release?

http://ftp.netbsd.org/pub/NetBSD/NetBSD-6.1.3/CHANGES-6.1.3

Using a bootloader from 1.4.1, and after I had corrected my
isc-dhcp-server's bootp configuration, but without making *any* changes
to my mopd configuration except to replace the 6.1.3 file with the one
from 1.4.1,  I managed to get both the bootloader starting and the
complete system booting to shell for me to finish configuration. That
is, I'm certain I have a fully functional mopd and the configuration was
correct for both tests.

So if 6.1.3 works for you and not for me, I guess there's either some
difference in my mopd implementation from yours that matters for 6.1.3
vs. 1.4.1, or else some difference between the 4000/90 vs. 4000 VLC. Any
suggestions as to what I should look at next?
