 surpriiise!  i take it they're aware that those buffer overruns - a
stupid bug which i fixed in the 3.3 a20-dev code i initially tested -
probably resulted in allwinner's employees going down a whooole slew
of increasingly-desperate modifications to the A20 USB codebase, when
in fact the problem was simply stack/memory corruption?

 yes.  i'm running fel-boot, that works fine, loads off the uSD....
buuuut there's nothing on the NAND (i wiped it).  that's a little
different from bootstrapping from android.
