Thanks! I learned about and worked through the qdbus commands and they work great from the command line.
I ran squarely into the khotkeys bug again when I entered these qdbus commands into the "input actions" menu of "system settings". After programming each multimedia key, I found that pushing the "Try" button worked great, however, the media keys still didn't do anything. I did not realize the "systems settings" menu used khotkeys, which as you pointed out, is broken in KDE 4.1.
I went on to set up things in "keyboard shortcuts" which is under the "keyboard & mouse" menu. As I programmed each key, it complained that the keys are already programmed into khotkeys, but since khotkeys is broken, it doesn't really matter. Also, using this submenu, I could not program buttons for a media player, but it did get kmix responding to the volume and mute multimedia keys.
Specific settings I made for my Dell M1530:
Assign "Volume UP" to: Increase Volume - PCM, HDA Intel
Assign "Volume Down" to: Decrease Volume - PCM, HDA Intel
Assign "Volume Mute" to: Toggle Mute - Front, HDA Intel
I tried assigning "Volume Mute" to "Toggle Mute - PCM, HDA Intel", but that didn't do anything.
