Subject: Keyboard and mouse issues on MacBook Air (4,2)

Hello LKML,

after several days of reading various forums and mailinglists,
it seems that keyboard and mouse support on the MacBook Air is
pretty broken:

- The fn key does not modify the cursor behaviour:
  FN+Cursor up should result in Page up,
  FN+Cursor down should result in Page down, etc.

  Actual result: Cursor keys are passed in as usual

- The multitouch trackpad only works if bcm5974 is loaded before usbhid
  -> otherwise only left click works

- If bcm5974 is loaded before usbhid, left moving the mouse while
  holding down the mouse button (i.e. the trackpad) does not work,
  but results in a right click

Anyone a pointer on how to fix these issues?

Cheers,

Nico
