Using the pktcdvd sysfs interface
---------------------------------
-Since Linux 2.6.19, the pktcdvd module has a sysfs interface
+Since Linux 2.6.20, the pktcdvd module has a sysfs interface
and can be controlled by it. For example the "pktcdvd" tool uses
this interface. (see http://people.freenet.de/BalaGi#pktcdvd )
