[linuxdc-dev]Puru Puru update

[Adrian M. <ad...@mc...>]

Those who are subscribed to the cvs list will now know I've posted an update 
to the Puru Puru (rumble) Pack driver - the change does not affect 
functionality in any way, but (in theory) should make for better use of the 
DC's resources.

A unified patch is below....
