Recently Raspberry company released a new version of Compute Module, 
named CM3 (Compute Module 3).  I already used the original CM1 version 
in an old project.  I think Raspberry solutions are very good if the 
project provides an HDMI interface, otherwise I think there are better 
solutions at a similar price.

In my current project, where I need an Ethernet interface, CM SOMs 
aren't good because, as you wrote, Ethernet is not CPU native.

The cheapest embedded Linux SOM I know is A13-SOM-256 from Olimex[1]. It 
is sold for 18EUR (12.60EUR@1000pcs).  It is cheaper than CM1 and CM3 
from Raspberry.
However A13-SOM-256 (and is big brother A13-SOM-512) doesn't provide 
Ethernet connectivity (I think because A13 CPU from Allwinner hasn't 
this feature natively).

We need the A20-SOM to have Ethernet connectivity, but the price rises 
to 40EUR (30.10EUR@1000pcs).
Maybe adding a USB/Ethernet bride (such as LAN9512 from Microchip) to 
A13-SOM-256 is cheaper than A20-SOM (but I don't know what the 
performance will be).

Another nice SOM is CORE9X35[2] from CoreWind.  It is a SMD SOM running 
Linux and provides and Ethernet interface with integrated PHY. The price 
of the model with 256MB is only 36USD (32.4USD@1000pcs)
