I just got a quote from the shop.  They can provide the Dm9161AE
(ethernet phy) and mount on the prototype board for $5 additional.  The
prototype boards are $5 to $10 each, depending on size.  Mininum order
of $50.  See:

We are getting some for $3 each.  How many do you need.

SAM7X samples has been seen!

There are distributors with samples right now...
If you download the evaluation kit manual ,then there are some schematics 
with a Davcom PHY.
You probably want to use RMII to save pins.
If you need industrial temp range, then the Davicom part will not cut it but 
a micrel part cn do
RMII + industrial.
