I have the same problem. NetworkManager eats up most of the CPU and after some time the system becomes quite slow. If I kill it with killall -9 NetworkManager and start it again it is OK. But this has happened to me several times already!
I am running Kubuntu 7.10 (with all updates up to today 2007-11-23) on a Dell Latitude D510. My wireless card is Intel PRO/Wireless 2200BG and my LAN adapter is Broadcom 440x. I have found several similar bugs in Launchpad and it seems that they are all related to NetworkManager problems after system suspend and/or wireless. Well it seems none of them was seriously evaluated so far.
