udev 096 problem

Hello! I've recently updated udev 095 to 096 from the ports tree, and my system hangs on XWindow starting. (no mouse, no keyboard, hard reset) I couldn't figure out what's wrong, but it's something to do with the udev rules. I've tried an older 50-udev.rules file and Xwindow works well. Could somebody help me with that plase? thanks kodiak
