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…
