Sorry, a summary of the problem:

The system frequently comes into a state where outgoing packets are
held somewhere.  The condition persists for seconds to minutes.  It
goes away by itself, but some of the packets are usually lost.  This
occurs on ath, FreeBSD 7.1-REL, no SMP, with kern.hz=100 (but not with
hz=1000).  Original mail with description can be found here:

http://lists.freebsd.org/pipermail/freebsd-mobile/2009-February/011343.html

I have done some more investigation, inserting debug prints in
ath_start (if_ath.c 1.177.2.2.2.1), one just after IFQ_DRV_DEQUEUE
(line 1576), another just before the call to ieee80211_pwrsave (line
1614).

Packets are dequeued, but ieee80211_pwrsave is called and nothing
happens.  Below is the output from "athdebug xmit" with these extra
two DPRINTF:s during the queue-up.  Then after a while packets are
sent again.
