K100D Anti-shake and K-mount lenses?

I am thinking about going from Canon G3 to Pentax K100D (or maybe DS?) because I still have from the old days my 1.8/50mm and a 300mm K-mount lens for the ME-super.

Now I wonder if the AS technology only works with the DA lenses (I read at http://www.popphoto.com/cameras/2566/hands-on-pentax-k100d.html ) "The system will work with any Pentax DA lenses and is projected to work with all of the Pentax 35mm system lenses"

Does this mean that AS only works with DA lenses?
