(The "plain" 650 [with 961] has no EHCI; this was introduced with the 962)

What about gathering all that info from the routing table? Please excuse
this perhaps naive assumption, but isn't that what's it's good for?

That's what's I'm telling ;) Now (in my office) I do not have the machine
to play with (personal laptop) but tonight I'll make a patch that will use
the routing table info to discover the appropriate router selection.
