Either you've mis-typed the above or you are incorrect.  From cvs log
if_iwi.c:

revision 1.8.2.7
date: 2006/07/11 00:00:29;  author: mlaier;  state: Exp;  lines: +1525 -618
MFC iwi update:
  Sync with if_iwi.c 1.35, if_iwireg.h 1.12, if_iwivar.h 1.11
  Lots of changes.

  This version now requires net/iwi-firmware-kmod so we also bump
  __FreeBSD_version to use in the port.


That is, RELENG_6 has the revised iwi code and you must use the
iwi-firmware-kmod port.

Figure out why you are not loading firmware properly.  The firmware is
packaged as normal loadable modules you can actually pre-load them using
kldload.  Check things loaded normally with kdlstat and/or check the
console log msgs.  My guess is you are not loading the correct firmware
modules.  I think there's a debugging knob/sysctl for firmware(9) but
can't remember it off hand.

I've wanted to include the firmware in the base system for a while so we
can put all this firmware packaging stupidity behind us.  It just
requires having a click-thru agreement mechanism on first use or
possibly just the intel README file in the directory.
