No one responded to my email.  I figured I got a little too intense and
decided to let it go.  Didn't want to be the ranting a-hole (too late). :-)

If you're interested, I still have a few ideas.  One was to wire two USB
serial adapters end to end to create a different console
(console=/dev/ttyUSB0,115200, getty, etc).  Since they would be going
over usb, that's a different clock, so it should work and provide us
with a safety net.

I'll see if I can dig up a few spare cables and try it out over the next
few days.  Priority is to get the pull requests for v3.9 in, though.

thx,

Jason.
