Power Management woes

[Firepowerforfreedom]

I'm having a struggle with both of my T40-series (T42 and T43, to be exact) ThinkPads: when I check PowerTop, I get this list (on my T43; the T42 is similar but has a Radeon Mobility 9600 rather than GMA900):

The "Wireless power saving" entry is a driver issue with Ath5k (power management apparently isn't quite working yet), but I'm at my wit's end trying to diagnose what's the deal with the other "Bad" entries.

Help?
