I have just verified that the current CVS version routes your test board 
just fine. There is no need to place vias for the SMD ground 
connections. The auto-router will do that for you. All that is required 
to use the plane is for you to connect at least one connection in the 
net to the plane so that the router know which net the plane belongs to. 
For your case, a thermal on J102 alone is sufficient.

Some day soon I plan to add a dialog to control the auto-router 
paramters so that you can adjust the cost (penalty) of each layer etc. 
That way you could create a "fake"  layer for jumpers and make the cost 
on that layer very high, yet allow the autorouter a way to use the layer.

Cheers,
harry
