There is only so much I can do and this one is rather far down the list because there are not that many users who are willing or capably of making a modification which is so complex and risky.
I would also like to point out that working with SW is in principle free, but developing hardware requires money to get PCBs made, components ordered and sometimes pay a technician to solder them. (I can't do 0603 let alone 0402 parts)
I get all that and I also understand that basically you guys are working for the educational environment, so making the Pi more power efficient is way back on the list. That said, it's plain obvious that for a lot of uses a more efficient power solution is necessary (not excluding educational uses). Tell wasting 40% of energy to someone trying to run the Pi 24/7 from environmental energy.
So would it be possible to add efficient powering the Pi to the Gertboard? I seem to have learned power can be applied to the Pi using the GPIO pins although that means you're on your own as the fuses are circumvented. But you could add all that to the Gertboard to which it is, as I understood, not necessary to add all the options, only what's needed.
