This fix does fortunately not break the userspace interface.

The version string is just for information and should not be used to 
determine changing userspace interfaces. Thinking about your concerns it 
may be the best approach to remove this version stuff entirely, before 
people begin to use it in any weird manner :-/

I'll make a RFC on the CAN ML if it can be removed.

Thanks for the feedback,
