Michael,
the problem is that LILO knows nothing of specific loaders used by
other operating systems. All LILO can do is load the boot block from
the desired partition and pass control to it. NT's boot block knows
to load NTLDR.
Your lilo.config stanza should read:
other=/dev/hdb1
label=nt
table=/dev/hdb
loader=/boot/any_d.b
Good luck!
