That is correct and expected behavior.

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.

Input: mousedev - move /deb/input/mice to teh correct minor

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

When doing conversion to dynamic input numbers I inadvertently moved
/dev/input/mice form c,13,63 to c,13,31. We need to fix this so that
setups with statically populated /dev continue working.

I had the same problem and this patch fixes it (I even concurrently fixed
that in similar way).
