If anyone can give me a small general hints for what might be the cause 
of this problem, I could take a look at it. I already have some patches 
for tun.o (that needs to be sent to the maintainer), another one doesn't 
hurt :) But since I'm not yet too experienced with programming of kernel 
modules, any help would be appreciated.
