--- Comment #5 from Greg <freebug@greggyb.com> ---
The machine that was exhibiting this behavior is sadly no more. The motherboard
turned out to be on the fritz and had to be replaced.

I did not have a chance to do much troubleshooting beyond identifying the mobo
as at issue. (One RAM rendered the system unbootable if populated; half the
onboard USB simply disappeared after several hardware swaps as par of
diagnosis, and some other gremlinish behavor). I chalk my issues up to the
failing hardware.

Nonetheless, with new hardware the -qn version remains functional. I've
reverted back to -qm as that also works.

To answer the specific question, of the binary combinations between '-n'/'-m'
and 'vmm'/'vmm.ko', only '-m vmm.ko' fails, as expected.

$ kldstat -n vmm
Id Refs Address                Size Name
 4    1 0xffffffff82167000   579de0 vmm.ko
$ kldstat -n vmm.ko
Id Refs Address                Size Name
 4    1 0xffffffff82167000   579de0 vmm.ko
$ kldstat -m vmm
Id  Refs Name
  3    1 vmm
$ kldstat -m vmm.ko
kldstat: can't find module vmm.ko: No such file or directory
