I can't get Pages to work in 2.0. I've tried switching around the permalink structure. Regardless of which structure I choose,
http://bill.simonifamily.net/contact/ always gives a 404 and
http://bill.simonifamily.net/?page_id=302 always works.
My .htaccess file has permissions set to 666.
Added: Last point that may be relevant. The 404 page isn't in the theme format - just a plain error message.
