This is done to synchronize the position of the mouse cursor on the client desktop with the mouse cursor position on the server. Mousedev is not designed to pass those absolute events directly to X, but it can translate them into relative movements. It currently does this for tablet like devices and touchpads. This patch merely tells it to also include a device with ABS_X, ABS_Y, and mouse buttons in its list of devices to process input for. This patch enables the mouse pointer to move when using the remote console.
