I will try to give it a spin over the long weekend.  Other testers please 
note that you should test this without ALTQ_NOPCC.  Looking at the patch 
now, it seems that the eventhandler should take this into account, too.  
i.e. when ALTQ_NOPCC is defined we emulate a 256Mhz clock with 
microtime - this shouldn't be dependent on the real cpu frequency 
(eventhough things will get strange when the clockspeed drops below 
256Mhz).  Sorry for not paying attention when you posted the patch.

CC'ing freebsd-pf@ ... laptop anyone?
