My server is running PHP 5.3 and my WordPress install is spitting these errors out on me, causing my session_start() to break.

Deprecated: Assigning the return value of new by reference is deprecated in /home//public_html/hub/wp-settings.php on line 647

This is annoying, but I do not want to turn off on screen error reporting. How do I disable these bothersome deprecated warnings?

I am running WordPress 2.9.2.
