Hidden Text

What is the best way to hide text/links on your page without having it devalued by google? Need to add some more text to a flash site where and not have it affect the layout of the site.

Can imagine visibility : hidden is probably not the best choice, but what about offscreen positioning, overflow:hidden ect? any of these work without getting the text devalued?

if me, i am using <noscript>your text or links here</noscript>

if link >> google count it as backlinks
if text >> google see it as a content.
