The volume buttons should be supported by either acpi controls or
keyboard settings.  Try running showkey and seeing if they trigger
keycodes.  Once you have those, you could map them to a macro that
adjusts volume through amixer.  I know that there are applets for KDE to
support the thinkpad keys, there may be others as well.
