SuSE Linux has a nice KDE kioslave for system information called sysinfo:/
Seems like it is only available at SuSE Linux. Anyway, after googeling a bit I downloaded the kdebase3 RPM, extracted the corresponding code, and after emerging hwinfo (masked by ~x86), I was able to compile and here we are! Works really good, except the display stuff, but thats stuff of my Laptop…
Sourcecode btw…
Here are the packages http://www.kde-apps.org/content/show.php?content=58704&forumpage=4&PHPSESSID=0163dd596e5fbc7fd991a1b143ac5c13
