ok, i'll definitely give that a shot, but i'm still curious as to why
the wireless interface insists on grabbing *both* eth0 and wlan0 on
that system when, on another system of mine, eth0 is assigned to the
onboard intel ethernet controller, while the wireless interface is
content with just wlan0.  somehow, the first result just seems wrong.
