I rewrote it to not use Xosd and added support for the multimedia keys with Amarok.
Amarok has got it's own OSD so Xosd was not needed.
It should be very easy to modify it to support any media player that supports dcop or similar command line client, it would be a matter of just changing a few strings.
Original code and posts can be found here - http://ubuntuforums.org/showthread.php?p=2610422
In hopes that someone might find this useful I add the code here
sk8135-pcm_plus_mediakeys.c:

*-------------------------------------------------------------------------
* by Mathieu Virbel, for sk-8135 keyboard (25/11/05)
* based on http://www.frogmouth.net/hid-doco/c537.html examples.
* Rewritten by Fredrik Larsson <ekerim at gmail.com> (31/05/07)
* - Approx 95+% of code rewritten
* - Removed dependency of aumix
* - Removed dependency of xosd
* - Added dependency to Amarok
* - All media keys works on Amarok via dcop system call
* - Added support for all the media keys (other special keys not handled)
* Modified 01/06/07 (Fredrik)
* - Removed unnecessary if-else handling mute differently then other keys.
*
* Even though I know this is kind of an ugly hack I thought perhaps someone would find it useful.
* Using system() to interact with dcop and Amarok is not the most elegant way.
* I will most likely write a KDE app with a nice little tray icon and much more flexibility when KDE4 is released.
* Have fun.
*
* // Fredrik
*
* You need :
* - kernel headers (Tested with Gentoo linux-2.6.18-suspend2-r1 kernel source)
* - X11 (Tested with xorg-x11-7.2)
* - KDE (Tested with 3.5.5)
* - Amarok (Tested with 1.4.5)
* - Read rights to the correct event device (modify the udev rules and make the events MODE="0644")
*
* Compilation & Installation:
* gcc sk8135-pcm_plus_mediakeys.c -o sk8135-pcm
* mv sk8135-pcm /usr/bin/
*
* Test example:
* Use 'cat /proc/bus/input/devices' to find the Dell keyboard event devices and try them all (usually two of them).
* My correct device was /dev/input/event5
*
* nohup sk8135-pcm /dev/input/event5 >/dev/null 2>&1 &
