Thanks for the patch. Three request for your next patch:

1) It seems like your mailer, M$ Outlook, corrupted the patch,
   probably wrapping lines etc. So i had to apply the patch by
   hand. Please could you either use attachments or upgrade to a none
   corrupting mail tool.

2) You made the diff in the ramfs src directory. Please could you do
   it from the package directory in future. It just makes it clear
   exactly which file should be patched.

3) Please include a ChangeLog entry. I added one for you this
   time.

Here is what i committed.

     Thanks
        Andrew
