Worked like a charm!  Everything worked exactly as you described, 
including the occasional screen flicker (except the screen idle time 
seems to be nearer to 5 seconds than 10).

Removing the drivers entirely is a very interesting proof-of-concept.  I 
am still amazed at the amount of investigative research that you guys 
still do, considering how mature the project is!  It's never boring 
around here.  :^)

One very minor quirk I noticed: it seems that before blanking the screen 
every second time, it goes back to the default setting for screen 
brightness.  I normally set mine to level 2, and after the first wake-up 
it stays at 2, but immediately before sleeping the next time (barely 
visible for a split-second) it goes back to 4.  Not a problem; just 
mentioning it in case it illuminates something deeper.

My biggest observation is how easy the on-device update process is. 
Thanks a million for implementing this!  It reduces the barrier to 
basically zero.  I have very little free time these days, but even I can 
press a few buttons and test something new!

Please keep the test updates coming!

  Thanks!
