Maybe you still have kpowersave installed? It should be obsoleted
since KDE-4.2 which introduced PowerDevil (packaged as part of
kdebase-workspace, check you have it installed).

Network connectivity -- note there are two systems:
1. Network Manager - Since F8, became default since F9.
2. The legacy network scripts.

First, make sure they don't fight each other:
  chkconfig --list NetworkManager
  chkconfig --list network

Only one of these should be enabled (normally NetworkManager).
If you want NetworkManager to use your older system configuration
simply choose "system eth0" instead of "auto eth0". This setting
uses a distro specific backend to run the legacy scripts (F9 made
NetworkManager default after having this backward compatibility
layer).

If it persist, aside from reporting this bug against Fedora bugzilla
there are two upgrade paths that may help you:
1. Upgrade to F11 (KDE-4.3) in two weeks (9/2) and apply the 0-day
   updates.
2. Wait a little longer, as KDE-4.3 is planned to be pushed to F10 after
   the release of F11.

Hope it helps,
