I'm using xmonad and xmobar exclusively with my own power/display/system
management, acpi and hotkey scripts. No desktop environment.
My acpi handler is as minimal as possible as I currently prefer to deal
with most keys via xmonad directly. Here it is:
https://gist.github.com/4582988
My xmonad config is here
https://github.com/altercation/es-etc/blob/master/xorg/.xmonad/xmonad.hs -
See the "keysMedia" and "keysSystem" and "keysSystemCodes" functions for
how I handle them (including the battery key which, in this case, doesn't
have a functioning symbol).
This is all on Arch Linux, 3.6 kernel.
If useful, you can see my "system" "displays" and "power" bash scripts in
this repo: https://github.com/altercation/es-bin They are all from scratch,
minimal bash scripts to handle almost everything a normal desktop
environment does, specific for my thinkpad, but relatively adaptable to
other makes/models.

Nothing reported by xev? there are lower level ways of defining hotkeys
which can be tried. it may take some work but even in cases where there was
absolutely no response I've been able to eventually assign proper behaviors
to most hotkeys on this and other thinkpads. I'd be happy to detail the
methodology as best I can that I used to sort this out in the past.
Best,
