Yes, it works for me properly (testing with rc4+, 1b42fc4 more precisely). 
Even after disconnect/reconnect cycle of USB mouse, I am getting events 
properly from /dev/input/mice (frankly I am surprised that you noticed ... 
Xorg has been using evdev driver for ages already by default, right?)

What was the last kernel version that worked for you in this respect?

Adding Dmitry and linux-input.
