After a recent git pull and kernel build and reboot, Xorg could not find 
the input devices and I was left with unresponsive mouse and keyboard 
until I could remotely shut-down and boot into an earlier kernel.

With good kernels, Xorg.log showed evdev finding the mouse and keyboard.

Bisecting lead to this commit:

     Input: allow matching device IDs on property bits

     Let's allow matching input devices on their property bits, both 
in-kernel
     and when generating module aliases.

I am happy to run further tests if needed.
