Using it as a server on if I need a local connection I use the serial 
console via a TTL/USB converter.  Of course I would have to get the 
pin-out for this board.

Ouch. this is for a mail server that has extensive disk I/O.  So forget 
this board.

Any timing on delivering the support mainline?

I will look at it.

I use to follow it closely and did some testing for Hans when he was 
running the Allwinner development.  I should go back and check in, so to 
speak.

Of course if there is a quad core 64-bit ARM with sata under $100 that 
runs at 5V; that would do nicely!
