I have discovered a better way to reverse the function keys. It turns out
that the keys can be reversed by the setting the fnmode parameter to 2 for
the apple_hid kernel module. This can be done by for example

# echo 2 >/sys/module/hid_apple/parameters/fnmode

One advantage with this method (as opposed to the reversed keymap files)
is that the function keys remain reversed with X11 as well. The apple_hid
kernel module needs to loaded regardless.

Therefore I suggest that we remove the map files named apple-*-reverse.*
and instead refer to the use of the fnmode parameter. Would you agree?
