Chris, after a little more research, it seems the problem is kernel related. The previously described behavior of kpowersave only occurs with kernel 2.6.23.8-63. The same version of kpowersave works ok with kernel 2.6.23.1-49.fc8. I also have other problems with the newer kernel (can't connect to wireless networks using iwl3945 and sounds are being played with echoes). []'s Marcelo
