What platform are you on? I can think of several programs that fit at least some of this bill:
Emacs with Org Mode and deft
Zim
Circus Ponies notebook
Devon Think
Notational velocity with its wiki like linking
Tomboy notes
many more that I could list with time
Some of these will have various limitations such as not supporting images or not allowing easy drawings, etc, but many would come without the overhead of wiki markup.
