you can extract Pentax profile from in camera DNG yourself, or download from here :
deejjjaaaa: DNG (.dcp) profiles (OEM, invariant & untwisted) : Pentax K-x & Pansonic Lumix DMC-LX3
then put it where it belongs, for example (Win 7) to : C:\Documents and Settings\All Users\Adobe\CameraRaw\CameraProfiles\Camera\Pentax K-x
