  well if you want to make it work then feel free to ask any
  developer who willing spent their time to write the code and it will
  be great if you can donate the hardware also.
  i think ru@ and glebius@ is the guy who currently proactive develope
  the polling(4) code.
  the recent work for polling was additional support to bge(4) which
  have been merged to RELENG_6 (work done by glebius), we've been used it on our production
  router seems pretty robust.

  finger glebius at freebsd.org
  honestly he is my FreeBSD network hero :)
