Actually, no they didn't. (Not sure why Slashdot posted that without verifying it...). According to Sun's FAQ on Solaris 9 Early Access, it says:

8. Why are there no media or download options for the Intel version of Solaris 9 OE?

We are defering the productization and release of Solaris 9 OE for Intel IA-32. Sun[tm] will continue to ship existing and new versions of Solaris 8 OE for Intel. We have made this decision for business reasons.

I know there are beta versions out there, as I have talked to a customer running it on their Intel server.
