Note that this will give any setgid kmem program _full_ (read and write) access to the io registers (since open() is the only important action for this device). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
