Where is the source?

[reg at dwf.com]

I am obviously missing something, but where is the source
for the PC-BSD kernel.  I dont see it on the DVD release.

I need it to build a NVIDIA driver for my video card.

Mabe I just dont understand the wording of the descriptions 
of the various files, but I dont see it.
