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.
