Unfortunately nobody done with these keys. Typicaly USB multimedia
keyboards
use secondary USB interface especially for multimedia keys. You can parse
/proc/bus/input/devices and make sure by Yourself. One keyboard ware have
two physicaly interfaces, each have /dev/input/eventXX device.

/dev/input/eventXX is done. You may download CVSed evtest.c and test
Your multimedia keys.

I don't know any userland util , which read /dev/input/eventX and do user
configurable orders.
I don't know any userland util , which read /dev/vc/XX multimedia keypress
and do some important.
Under ruby 2nd USB keyboard interface have another VT and You do not
recieve keypress from multimedia keys. Typicaly mutimedia keypresses are
ignored by keyboard driver. TTY may recieve multimedia keypresses as 4 - 6
keycode series. That series already decoded by /dev/input/eventXX layer.

If anybody has a developer power, then is possible merge evtest.c and
http://xkeymouse.sourceforge.net/ utils and so catch multimedia keys.

AFAIK eventXX layer works indenticaly with bunch of keyboards fitted with
multimedia keys (Microsoft, Logitech and so on).

Can You drop a note to me, how to decode <0x00> <0x01> <0x14> <0x00>
sample keypress sequence ?

doesn't "xev" give you the keycode ?
i also found "xbindkeys" which seems definately nice,
but i'm not sure how well does it play with multi-user environment

IIRC some months ago Aivils added :
echo "+$PHYS"  > "/proc/bus/console/$VT/keyboard"
to join additional keyboard interfaces, so you'll basicly have to
use a modified input.agent to map the xxxx..../input1 (multimedia key
interface) to
the primary keyboard interfaces xxxx...../input0 and then XFree will get 
all key events, you only have to create your custom key map to map
the additional keys to XFree events(XF86_WWW,XF86_MAIL,....)
and then configure XFree/WindowManager to use them, 
ie start evolution on pressing XF86_MAIL, Mozila on XF86_WWW, ...

you may take a look at

Ah cool, that sounds just as what I was looking for. It did not work direct=
