Hi, does anyone know, where I can get the kernel-source from the installed kernel? uname -r says 2.6.23.9lw and I think that this is a patched kernel. I just need one additional module called "airprime". I think the most easiest way to get everything running is, to take their kernel-source and compile it with their config (which is available in /boot/config....) and just enable module-support for my needed module. Thanks, Monkey
