Every time I put my 12" PowerBook (RevA) to sleep and wake it the display is set to the awful washed-out factory default calibration and I have to open System Prefs and set it each time, it's getting quite lame. I'm not losing anny other settings so I don't think it's a battery thing or anything. I've fixed permissions, run fsck -y, etc. I sent a report to Apple, just thought someone here might have an idea I hadn't thought of.
