power saving

[Tania Oka]

I would like to reduce power consumption on a custom MPC855T board.  I
notice in arch/ppc/kernel/idle.c idled() that the power saving code
seems to be skipped for processors other than 603/750 types.  Can anyone
tell me why that is?  Is it not a good idea on the 855 for some reason?
Is there anyone who has tried this on the 855 (or 850 or 860)?  Any
comments on the general subject welcome.

Thanks
