I was getting a lot of network conflicts coming out of suspend mode, as the IP address was being reassigned to another computer on the network (i.e, loud screeching noise from my girlfriend). Turning off the connection (eg, "sudo ifconfig eth0 down") when going into suspend mode solved the problem. (I have to turn off OSS sound as well. so added it to my suspend script). Turning it back on gets a new IP address without the need to reboot. (eg "sudo ifconfig eth0 up; sudo udhcp -i eth0"). Think I'll add an eth0 button to my dock..
