That does not seem right to me.  I think that with the above it should
all work okay.

Change the 'auto eth0' line to 'allow-hotplug eth0' instead.  That
triggers the dhcp to happen when the device becomes available.  That
will probably workaround whatever problem you are experiencing.  The
allow-hotplug is now the default in Etch.

I think it should already be trying again periodically.  Perhaps the
timeout is very long.  You might try dhcp3-client instead.  I have had
good luck with it.

I am suspicious that something else is also involved here that is
causing confusion as to what is really happening.

Sure.  Laptops operate that way a lot!
