What you see on FreeBSD is that the Magic Mouse works as a normal mouse, 
without any of the touch screen thing. I guess in X you can emulate a 
middle click by chording (though I don't remember if the mouse will send a 
left-and-right click event in basic mode).

I'd say that using the NetBSD driver (I am the author) is not really 
possible on FreeBSD, since FreeBSD does things related to Bluetooth HIDs 
differently. It should be simple enough to add the Magic Mouse handling to 
the bthidd(8) daemon though, but I don't know how easy that would be, or a 
separate daemon could be written instead.

The way I worked the identification in NetBSD, was that when configuring a 
HID device, I checked the descriptor as normal and also the 
Manufacturer/Product ID via the PNP profile. When the latter matched the 
Apple Magic Mouse, then it just attaches a different driver.

The Magic Mouse then needs an initialization command to be sent via the 
standard HID protocol "SET_REPORT(FEATURE, 0xd7) = 0x01" once connected to 
enable the special extra functionality that it provides.
