Just finished updating from r238227 to r238290 on the "head" slice of my
laptop, and was unable to make use of the wlan(4) NIC; I captured the
following via cut/paste from ttyv0:

Yesterday, I had updated to:
FreeBSD g1-227.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #614 238227=
M: Sun Jul 8 06:47:51 PDT 2012 root@g1-227.catwhisker.org:/usr/obj/usr=
/src/sys/CANARY i386
and things seemed OK -- I was certainly able to use the NIC. :-}
uname output from this morning:
FreeBSD 10.0-CURRENT FreeBSD 10.0-CURRENT #615 238290M: Mon Jul 9 05:39:1=
5 PDT 2012 root@g1-227.catwhisker.org:/usr/obj/usr/src/sys/CANARY i386
I glanced through the list of commits to head in that range, but
didn't note anything glaringly obvious (yet).
I hadn't tried a wired NIC on the laptop; I can, if there's anything
likely to be of value in doing so.
I've attached a copy of the associated dmesg.boot.
Peace,
david
