OK.  I think something like this is needed, though.  If you have an 
application that actually "knows" about the dial axis that's fine, but 
in most cases you'll want to do some sort of mapping.  I don't see any 
mention of the mouse scroll wheel in the new evdev man page; how is 
that managed?

The old driver was ugly (bitmasks etc) but useful.  I hope the new 
version hasn't "thrown the baby out with the bath water".
