allright, going the right way, but not there yet. now I get "bay  beep   
bluetooth  cmos  dock  driver  hotkey  led  light  video". is my version  
not uptodate?
is there anyplace where documentation about getting this rmmod/modprobe to  
be a system-standard behaviour, and not always user-controlled?
