Hint: with enough ram you can disable the HD altogether. Copy a compressed  
HD-image into ram at startup and use that as / (initrd, unionfs, squashfs  
and you´r set). copy back anything you need before shutdown using rsync.

Here: R51, 9.5W at idle desktop. I think that T42 is a execption.

yes. (i´m using it myself)

If you can use fglrx and don´t mind the closed-source nature: forget about  
dyn-clock and rovclock. The open-source solution cannot change the GPU  
corevoltage and cannot disable some GPU festures. Properly installed fglrx  
does all that (=Powerplay).
