Hi,
You can grab a PSM demo from nvidia's website that I believe implements all of Simon Kozlov's improvements here:
http://download.developer.nvidia.com/developer/SDK/Individual_Samples/DEMOS/Direct3D9/PracticalPSM.zip
I think you'll need the rest of the nvidia sdk to run it though.

Tessellator,thanks.
i download it,it's version is 1.0,in the paper of NV GDC 2004 PSM paper,the screen shoot show it's version is 1.1.
Perhap NV don't offer the version 1.1 download.
The version don't use the inverse projection matrix for virtual camera which mention in Simon Kozlov's improvement.
My english is poor,only read the paper,i can't understand how to use the improvement.
Someone know a source code implement the inverse projection matrix of PSM?
Thanks.

Hmmm, I recommend to use Light Space Perspective Shadow Maps(lipsm), cuz to do PSM well, lots of horrible hacks are reuqired. In addition lipsm provides src code on its website.
