10.4.2 disabled hardware fn keys on powerbook?

[Cali_Man]

Title pretty much says it all, ever since installing 10.4.2 on my powerbook 15" 1.5 the fn keys (which are set to control hardware features in system preferences) seem to go from enabled to disabled between resets. Curious if anyone else has had/noticed this problem....

I don't have that problem. Did you try repairing permissions? Or reinstall the 10.4.2 update (you can get it from the apple site).
