It would be interesting what the output of the commands

  ifconfig -a

before and after a sleep/wakeup look like.

I suspect it's an initscript and/or hotplug problem rather than a net-tools one.

Hm, looks really like hotplug doesn't reactivate the interface after
wakeup, e.g. that the kernel might not even get a hotplug event from
the laptop resp it's network card.

This can happen on some laptops, and unfortunately the only solution
for now is to restart the network manually via

service network restart

from a root shell.

Hope that helps,

Read ya, Phil
