I tried setting up the 3G modem and getting it all configured, and closing
the ttys during suspend - no change.
I tried getting rid of 'getty' on /dev/ttyO2 and everything will a real tty
open.  No change.

But then I used alsamixer to turn everything down to 0 and mute everything
and - hey presto - suspend current is about 25mA.  Awesome.

So thanks again for reporting that.  I never would have found it if I
hadn't looked, and never looked if I didn't know for certain there was
something to find.

So: only another 20mA to go...

25mA should be must more than 24hours (which is more than I ever got with the
freerunner, as I never for the #1024 fix).
