This will also be true for the IBM 405LP (starting with the "Beech" eval
board), which has a number of new PM features (
http://www.research.ibm.com/arl/projects/papers/405LP.pdf ).  IBM has
internally used a pm_idle function pointer a la i386, hoping that would
be the community-accepted way, in case ya wanna add that to the
suggestion pile, but I think any of the methods proposed would be fine.
