ACPI and KDE

[Bob Alexander <bob@ngi.it>]

I have installed a script which responds to Fn-F7 by issuing a 
radeontool dac on and off (toggle) on my Thinkpad T40.

How can I get some nice message box on KDE just like what I see when I 
give other ACPI events like echo level 7 > /proc/acpi/ibm/brightness (a 
nice grey box with "Brightness" label and a 100% bar under it) ?

I'd like to write the same nice box with External video on/off (and do 
the same thing for wifi).

Thank you,
Bob
