Media Keys on Inspiron 8200

[cbrito at optonline.net]

Has anyone gotten the media keys (volume most importantly) to work on an Inspiron 8200 running Warty?

I looked on the wiki, and it says volume keys work ( http://www.ubuntulinux.org/wiki/HardwareSupportMachinesLaptops/view?searchterm=Inspiron%208200 ) but no such luck for me, pressing them does nothing. Including using the Fn + Page UP/Down keys. Regular volume control through applets works.
