It works very well

parm:           emulate_3button:Emulate a middle button (bool)
parm:           emulate_scroll_wheel:Emulate a scroll wheel (bool)
parm:           scroll_speed:Scroll speed, value from 0 (slow) to 63 (fast)
parm:           scroll_acceleration:Accelerate sequential scroll events (bool)

Mouse sensitivity is very high but probably you would adjust scrolling speed:

sudo rmmod hid_magicmouse; sudo modprobe hid_magicmouse scroll-speed=47 scroll-acceleration=0

Changing “scroll-speed” parameter try the best for you then set it permanently creating a modprobe.d config file

# nano /etc/modprobe.d/magicmouse.conf

options hid_magicmouse scroll-speed=47 scroll-acceleration=0

You can swap axis in the usual way using xinput:

xinput set-button-map 'Apple Magic Mouse' 1 2 3 5 4 7 6

On Windows 8.1 installed via bootcamp it works out of the box

Not yet tested :) Obviously it works fine!
