How exactly did you disable the wireless? Was the ethernet cable already
plugged at that time? Was eth0 up?

What controls you networking stuff, "ifup" or "network-manager"?
Anyway, check your "/etc/network/interfaces" for "allow-hotplug eth0"
stanza. Also, review the messages with "tail -f /var/log/syslog" and
"dmesg | grep -i eth0".
