NOT derived from the Linux code and is thus not GPL'd. It is the author's express wish that the GPL copyrighted version be removed and this BSD copyright version take its place. Considering our own stance on this, I'm certainly not going to argue! [Note to NetBSD folks: You're free to grab it now :-)] Submitted by: Mikael Hybsch <micke@dynas.se>
