Commenter (if you read tenfourfox development blog you'll recognize the name) has just posted that tenfourkit (a modern, updated webkit engine for safari) is available now as an app for 10.4. Click to Flash works for youtube, but you must disable plugins, apparently. http://goo.gl/BFF29 I have no more 10.4 running macs to test it on, but would love to hear how it works. Maybe the luddite (macindan on this forum) will be willing post a review, as he is honest as abe lincoln and knows his 10.4. Long live the PowerPC.
