The pixel shaders are only 'techincally' not dx9 compliant. They _can_ do dx9 level work, but the DX spec calls for 4 shaders capable of doing a certain level of work, and the Matrox shaders appear to chained together so you only have 2 of them for more complex shading operations. (i.e. 4 simple shaders or 2 complex shaders, kind of like the decoder on the Athlon, it can issue a certain number of 'simple' ops a clock, or a smaller number of complex ops a clock)
so it can "emulate" ps2.0 at half speed?
This sig is a shameless atempt to make my post look bigger.

take a look on the ground. on the right side the textures are more blurry, especially in the distance. while this is not very visible i think it will be when the you start moving.
dx9 requires 4 ps2.0 units but parhelia´s 4 ps1.3 units can work like 2 ps2.0 units which isn´t enough for dx9 compliance, but any dx9 game that makes use of ps2.0 will run(slow) on it anyway, i guess this is transperant to the developer.
is this something all cards with 4 standard ps1.3 can do or are these ps1.3 special in that way?

This is the first time I've seen Pixel Shaders arranged like this, and it really it quite ingenious.. (other shaders aren't setup like this, although you might be able to emulate it via drivers, not 100% sure).
Fear not, I think when matrox moves to .13 they'll add the extra units in.. it doesn't look like it would be terribly hard to do..
Superfly:
By the letter for the law the card is NOT fully dx 9 compliant, however, the key point is that it can easily be made to be by Matrox, when they deem it necessary..

Normall I would never ever break an NDA as I was under one for Lord Of The Rings (worked at a post house that did it), but seeing as this was already out there, and giong to be posted in here anyway, I figured I may as well do it first.
