from what I have heard, yes the vader white ones are hackable.
as for chickHEN (aka HEN) you can't run ISOs on it but you can use 5.03GEN-A which will allow homebrew, ISOs, recovery menu, plugins and the vsh menu. all you have to do to use chickHEN is upgrade to 5.03 firmware and download this: ChickHEN Homebrew Enabler R2 Download read the readme and do what it says. then download and run this through chickHEN: File Details-CFW-5.03GEN-A-for-HEN-PSP -
