If there are specific golf 'channels' out there or particular events, I would go to their websites and look to see if there are any iPad apps - they may well be subscription based though.
Also if there are apps, check out reviews in iTunes or the developer's sites as many apps with copyrighted video will only send audio to AppleTV so best to find out before subscribing to anything.
How do you watch these channels/events now?
