[PATCH] fix apple alu keyboard with numpad

[Dag Bakke]

The nice apple alu keyboards with numpads are pretty much unusable in
vanilla 2.6.25.
(http://images.apple.com/keyboard/images/gallery/wired_1_20070813.jpg)
Hitting the 'clear' key (=numlock) disables the numpad, and maps multiple
alphanumeric keys to numpad symbols in typical laptopkeyboard fashion.

Furthermore, some of the F-keys do double duty as multimedia keys. The
vanilla kernel defaults to multimedia keys, requiring the user to hit
the 'fn' key to get F-key events. I use F-keys more often than multimedia
keys, so I included the patch to change the default to be F-keys.

The following patch is taken from:
https://bugs.launchpad.net/mactel-support/+bug/201887
and appears to have been written by Eric Johney. I have merely lifted
the two patches from the webpage above and submitted it, as I couldn't
see it upstream after a brief search.

For "completeness" and the benfit of someone finding this in an archive
later, the following 4 commands provides correct keys for
the multimediakeys in X:

setxkbmap -model macintosh
xmodmap -e "keycode 162 = XF86AudioPlay"
xmodmap -e "keycode 153 = XF86AudioNext"
xmodmap -e "keycode 144 = XF86AudioPrev"

Works with a US layout keyboard, anyway.
