I updated the firmware, of course. As for bogging it down, I really don't see how that's possible. I've a 10Mbit connection and my router so far can use every bit of it, even when across multiple computers. My upload bandwidth is the same as my download. I can stream DVDs (both ways, if need be) but can't receive and send VGA quality video? If it was bogging it down, wouldn't it cap at my ISP limit rather than my router since my router is capable of speeds faster than my internet? Are Facetime bytes different from other computer bytes?
Something seems amiss. In the past 12 years or so of using wireless networks I've never had any piece of hardware or software "choke" down a router and cause it to reset. Every time I've hit some sort of cap, the software either adjusted quality, slowed down, or disconnected. None of these events caused my routers brain to short circuit and reset. I hope Apple can get their new toy to play nice with others soon, I really love Facetime
