If it's not on the Compatibility docs, then it's not "approved" for use, which doesn't mean it necessarily won't work, just that they feel it doesn't meet the requirements to even begin testing with it. You can definitely try it, and it may or may not work, but you're on your own if it doesn't, "not approved" means they don't help you if call tech support about it, they'll just tell you to get a compatible computer. If you're really lucky, there might be a user out there that has this exact combination who could tell you, but since it's not supported, I would imagine there's very few who have tried it. I've been in contact with several of the later G3 iBooks, and they barely run Photoshop at a decent clip, I don't think I'd even try it with PT7.
