Q) Does em0 work under HTT?

[Yamada Ken Takeshi]

  Hi!
  Does em{0,1} work under Hyperthreding enabled?
"em0", seemingly is not working under my environment;

FreeBSD 5.1-CURRENT #15: Sat Oct  4 09:46:38 JST 2003

However, I am not sure if it is because of HTT
enabled or not.

Any comments/suggestions are very appreciated.
