energy savings

[dylan]

hi-
a few open questions regarding power saving, myths about hardware 
problems, and linux.

1. what sort of powersaving options does one have with YDL and or 
linux in general?
i am aware of hdparm and pmud, but is there anything else for drive 
sleep, monitor sleep, and or system sleep?

2. it has always been my practice to setup my mahcines with 
powersaving in mind- disk spinning down after x minutes of 
inactivity, monitor sleep after x minutes, system sleep after x 
minutes.  i have never run into any problems with drives or monitors 
dying- and this is on a cross-section or various macs and pcs from 
1989 until now. besides the rumors or drive failure due to putting 
the heads to rest, are there any reasons not to impliment power 
saving? and are these rumors valid?

any input would be appreciated -
thanks in advance,
dylan
