As there was nothing else to do due to very bad weather conditions this 
afternoon, I dived into a kernel compile, following the guidelines in
https://fedoraproject.org/wiki/Building_a_custom_kernel
What an effort in time and disk space just to change a few bytes of code!
But I finally succeeded in building and installing a (reversely) patched 
kernel package: kernel-3.15.6-200.fan.fc20.x86_64, with the hopefully 
expected result.
Thanks
