Daniel,
The approach is pretty solid, with the exception that I do not think
we'd save much if we allocate every axis data separately (as I mentioned
in one of my earlier mails).
Coudl you please take a look at the following patches and let me know if
you see something wrong.
Thanks!

Input: add static inline accessors for ABS properties
From: Daniel Mack <daniel@xxxxxxxx>
In preparation for dynamically allocated ABS axis, introduce a number of
sttaic inline access helpers. This should make the transition less
painful.
