That's what I have at the moment, and NM gets itself in a tizzy when I
want to use eth0 as my primary connection and borks my non-local traffic.

Slightly more technically, the default route I define via eth0 gets
overridden/replaced to be via wlan0 at the point NM realises it recognises
the wireless AP. (To be a little fair, the documentation does warn about
this, but now we're back to the beginning of the thread.)

I've recently modified /etc/default/Network-Manager so that NM is
prevented from starting at boot-time if I already have a viable default
route via eth0. Ugly, but effective in my typical scenario.
