Re: gEDA-user: PCB Keep-out layer?

You can lay down  copper polygons in the regions you don't want
tracks to run (on each routable layer) before auto-routing, then remove
them after auto-routing. It's a tad kludgy but fairly easy to do.

The auto-router understands all exisiting copper and will avoid it; you
can hand-route half your board and auto-route the rest afterwards.
