From what I understand, instructions from sony will only help you expose the rootkit, following the instructions will not help you get rid of it. Read this article to see why:

This is the part people need to be aware of:
The patches that reveal the hidden files are being made available to antivirus companies as well as customers who visit the Sony BMG site. They do not remove the copy protection software, however.
This is the part that concerns filling out the application for instructions on how to remove the rootkit:
McKay said customers can request a program to safely uninstall everything by visiting the Sony BMG Web site at http://cp.sonybmg.com. That site, however, requires a form to be filled out and submitted.
In a test of the form late Wednesday, an e-mail confirming receipt was quickly returned by Sony BMG customer service, but it included no instructions on how to remove the software. The message promised another reply "shortly."
