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.
Well if he is a Kalashtar soulknife with the 1st racial substitution level (see above) he does not have the Wild Talent feat. He will have 1 pp/character level though.
That was why I asked people about "other" psionic race substitution levels to see how thngs mesh.
However, I do not think it is that big a deal and don't see a real problem with allowing a SK to manifest his mindblade with 0 pp. But either ruling is really filling in gaps that the rules don't adequately address.
