Yes, local, but what does local mean? Is it hardware related or local in the 
software?

Ok, this will be controlled by the BIOS, I suppose, and there is no way, to 
deactivate it ion the BIOS completeley as the kernel has to interact with the 
BIOS?

Yes, like I guessed above....

When I add "nolapic" to the kernel , then everything is working fine, but then 
one of the two cores disappeared. Would be nice, if I could have both cores, 
you might understand. :)

All in all, I can run the notebook (it is no need to put it into trash). It is 
an Amilo pa 2510, 2x1,7 GHz AMD Dualcore CPU, with 4,6 GB RAM and a 320GB 
harddrive. I am using it as my kali-machine.

And such bugs are also good to learn things.
