In answer to my own email--I loaded the lkm.ko kld to provide lkm support,
but that didn't seem to work either:

# kldstat
Id Refs Address    Size     Name
 1    3 0xc0100000 2e73a4   kernel
 2    1 0xc09cf000 e000     linux.ko
 3    1 0xc0b98000 3000     lkm.ko
# modstat
Type     Id Off Loadaddr Size Info     Rev Module Name
# modload nullfs_mod.o
ld: /kernel: malformed input file (not rel or archive)
modload: /usr/bin/ld: return code 1

I suppose this means it's running the ELF version of ld, not the a.out
version, but I really don't know enough about how it works to comment much
more on the matter.  :-)

Thanks,
Robert
