ATA power savings...

since ataidle from ports doesn't work with ATAmkIII I listened very careful
to another thread on a local mailing list and found a very interesting
It describes that (back then) some disks have a "delayed write" feature.
But much more important, there's a patch included which tells atacontrol
how to spin disks down.
I guess this was for ATAng.
Is there any reason not to include that into ATAmkIII?
Now that we have such a nice cpufreq meta driver in RELENG_6 I'd really
love to see the hungry HD spin down, ideally managed by powerd ;)
But even if the "delayed write" feature is problematic, the ataidle feature
really should make it into ATAmkIII before 6-RELEASE IMHO...
