I did some research into this and I believe Wikipedia is talking about the USB Battery Charging Specification 1.0 (Which is now up to spec 1.1)

Here's the spec:

Some tests of chargers that meet the spec (only tested mini-usb?):
Neo USB charger specifications and compatibility list - Openmoko

I wonder why they aren't making this information easier to find? If Palm's intention was additional revenue from chargers, why not just make the Touchstone wall adapter proprietary altogether?
