Hi there, thanks for this extensive support, i really apreciate it!
The device is running (a modified) version of openwrt [0xFF-Backfire Vienna 1.5 (r1075) / LuCI Trunk (trunk+svn7606)]
Which includes the package manager "opkg". For installing kismet I added this repository to the opkg.conf --> http://downloads.openwrt.org/backfire/10.03/ar71xx/packages/
which includes kismet-*_2009-06-R1-2_ar71xx.ipk

About building it myself.. I mean this device is not really a power-horse, its an embedded device, i'm not sure that it has the tools and resources to build something itself.. and also i'm not that experienced with building stuff myself ;)
