this makes the extra keys on most apple macbooks and apple
usb/bluetooth-via-usb keyboards work like they do in mac os. most
importantly, fn+up arrow does page up, fn+down does page down,
fn+left does home, fn+right does end, fn+backspace does delete, and
fn+return does insert. it also makes fn+f10 mute, fn+f11 lower the
volume, and fn+f12 raise the volume through the wscons/audio stuff
already in place.
i've only tested it on a 1st gen macbook air and on a generic usb
keyboard that didn't break. some of this code comes from freebsd
and netbsd.
please test on usb-connected keyboards, especially on any apples.
