Cool! I've been waiting for this for a loooooong time. Thanks to you,
Hans Peter and all of the folks who have helped!

Not on the FAQ:

Q: Other then no longer requiring giant [MPSAFE], what does usb2 give
   us?  Does it fix the battery-eating on laptops? Does it allow the
   system to reach C3 and lower sleep states? (These are at least
   closely linked issues.)

I have not been running current for a while and this might be enough
incentive to get me to kick the tires.
