If you look into KDE control centre you should see KHotkeys under system. This is what is pointing your multimedia keys to Kmix. (Assuming KDE here...).

You can go into the Mentor Wireless settings, because they do the mapping for pretty much all of the keyboards. You will see increase volume and decrease. Theses are configured to do a DCOP call to Kmix, essentially a direct API to the application. Run KDCOP when you are there and browse the settings for Kmix. Kmix should be running for this so it can be queried. Your end setting should be of the form -

kmix
Mixer0
increasePCM
1

where DCOP calls Kmix, under Mixer0 remote object, asks for PCM increase in increments of one. I'm not sure if increasePCM is correct (On an XP machine right now) but if you're using KDCOP you should find some settings to suit your need. Don't be afraid to experiment before you press apply, just use the 'try' button to see if it works.

Those links are pretty good, but remember that the inbuilt KHotkeys is an extension of lineak. What should be remembered is that this is a way of overlaying two keyboard configs, if you don't mind a challenge you're better off configuring a whole keyboard definition. The default setting for multimedia keys is usuall the same as the Trust Multimeida Kb. Try that and mess around with it. It's info is under 'inet'.
