The apprentice rules for psionics were printed in the Mind's Eye, on the WotC website. If you download the .pdf archive of it (which I highly recommend) it's page 92. Here's what it says:
Psion: +1 Will, 2 Psionic Combat Modes. 1 power point (plus bonus PPs and 3 free Talents per day), and the 1st-level supply of known powers.
They also get a Psicrystal, but it only provides half the normal benefit, has INT 5, and only has the Empathic Link special ability.
Psychic Warrior: +1 Fort, 1 Psionic Combat Mode, 1 bonus Feat, 1 power point (plus 2 free Talents per day, but PWs don't get bonus PPs), and the 1st-level supply of known powers.
