I also think they're fairly clear and support irdeggman's initial response. How does a Soulknife power the mindblade? The answer is the Wild Talent class feature (bonus feat). Wild Talent provides two things: conferring the status of "psionic character" and granting a reserve of 2 power points. Which of these is necessary for the mindblade? Look at the remaining description of the class feature: "...if he has no power points otherwise." In other words, this clearly states (IMO) that if the character did have power points otherwise (multiclass), then the primary purpose of the class feature (i.e. to provide "the character with the psionic power he needs to materialize his mind blade") would be irrelevant.
The Wild Talent class feature supplies the power. The PP do not supply the power.
Does the Soulblade still have the Wild Talent class feature when he is out of PP? Yes. Hence, he still meets the prerequisite for powering the Mindblade.
Wild Talent: A soulknife gains Wild Talent as a bonus feat. (This class feature provides the character with the psionic power he needs to materialize his mind blade, if he has no power points otherwise.)
The rest of the sentence does not explictly state that power points provide the power, that's an inference.
In fact, turn the sentence around, but do not change a single word:
"If he has no power points otherwise, this class feature provides the character with the psionic power he needs to materialize his mind blade."
Hence, the original poster's question: If he is out of PP, then Wild Talent provides the psionic power he needs to materialize his mind blade.
This sentence explicitly states how his mind blade is powered without PP.
