How to use (sync) Apple Address Book with multiple accounts from Google?

Question

My impression is that by adding an "Exchange 2007" account to the Address-book does not work with Google Mail.

I tried to configure Google by using the iPhone method: exchange server on m.google.com but it doesn't seam to work.

I need to sync contact from 2 different gmail accounts (to be able to see and edit them as separated addressbooks)

Any ideas?
