Yes.

It does not ignore the OS these days; it's captured by a kernel driver,
converted into a key event, grabbed by gnome-power-manager, which
adjusts the backlight using I've no idea what (dbus and hal? xrandr?) and
shows a pretty pretty brightness bar on screen.

Sometimes.  At this moment Fn+Home/Fn+End do nothing at all on my
laptop, but I remember them working a week ago and not working two weeks
ago.  I'm clueless, but it's not a problem I feel a need to investigate
right now.

If you want to trick a pointy-haired boss into letting you write software in
Lisp, you could try telling him it's XML.
