Offhand it looks good.  Does it work?  If so, ship it! :)

Testing procedure was done using testjoystick. With a gamepad (a generic XBox 360 look alike, not recognized as a "controller") plugged in, I started testjoystick. Plugging in and out recognizes the joystick dissapearing and coming back.
With --disable-udev, testjoystick never notices the joystick going away, so I guess this is working.

A curiosity you are probably aware of, with the XBox 360 wireless receiver plugged in and the xpad module loaded, I always get 4 Xbox 360 joysticks reported by SDL, even though there's none "connected" wirelessly. It's probably related to the xpad driver though.
