CSS fixes/hacks for IE6

I have a page for a client with IE6 rendering issues. I need the page to render in IE6 as it does in Firefox or IE7. The footer in IE6 is coming out gray, where it should have the continuous gradient behind it. The page renders fine in Safari, IE7, Firefox 1.5x and 2.x and must continue to render fine in these browsers after your fix. The page must validate, too. There are two templates for the site: The homepage and a subpage template. NO tables allowed here - you must employ CSS techniques/hacks.
