I must say I've been seeing this since I use KDE 4(.0) on my current laptop, and that it still does this in 4.2 beta.
I never reported this because I tought of a hardware support problem (you know, the ACPI mess... ).
I am using OpenSuse packages for my part and my laptop is a Dell XPS M1330 too.
… and well, volume keys are detected as pressed, not only twice, but three times!
Sorry for this "me too" report, but I hope this will help finding the cause (I believe it is lower level than KDE, though… ).
