I found a script to handle LCD level changes via the toshiba hotkeys that you could modify to work with the additional keys:
| Code: | #!/usr/bin/env python
#
# Poll hotkeys of Libretto L1 series laptop and trigger appropriate events.

You can figure out what the hex code is for the hotkey you want to bind to by doing a watch on /proc/acpi/toshiba/keys and hitting the key you care about. Beyond that you'll need to learn some python basics and maybe some xmms command line tools to get it to do what you want.
