Ok, I've rebuit the system, and in my initial quick remote tests, tcpdump doesn't crash the system. Now I also admit that my test box on the 192.168.2/24 subnet isn't powered on right now, so who knows. I'll see if I can go back to 2.6.28 with USB_MON compiled in, and see if that causes a problem. Who knows... More later tonight if I'm lucky.
