Oh _YES_! I forgot this since I'm used to "tune" any HD I install with 
HGSTs DriveFeatureTool (under DOS) since sometimes these drives work on a 
real RAID Controller (like 3ware or ARECA devices) where I can't set any 
of these ATA features.
But in general I think anything that `atacontrol cap ad0` shows should be 
tunable with `atacontrol ...` in the near future...
Not to forget the possibility to read the drives temperature :)
And some documentation for end users needs to be done, especially for AAC 
and APM, I'm myself not really sure about the values...
But I'd volunteer to investigate...
