I've got a solution to get Saft running with Safari 3.0.3. Please take a look at my blog. For all non-German-speaking people: Go to /Library/InputManagers/Saft and show package content of Saft.bundle via context menu (I hope this is the correct menu item in english). Go to Contents and edit the Info.plist. Look for SaftSupportedSafariBuild and add a new array with a string with the value 522.12.1 Save the file and restart Safari. Now Saft will load correctly. This works for me from the first day of Safari 3.0.3 (now this will be 5 or 6 days).
