Thanks for posting - a useful hint! 🙂
Can't speak for Tiger but it works for Leopard.
But it does not solve a problem where a website, such as the BBC, not only requires the latest version of Flash Player, but still only works with Intel Macs.
For users of PPC Macs there is this workaround:
I cannot watch flash videos on the BBC website or on BBC iPlayer, although all other flash videos (YouTube for example) are fine.
For reasons that passeth all understanding, they work with the PPC version of Firefox, called TenFourFoxG5.app, once you have anabled plug-ins, as it does not natively support Flash.
You can download TenFourFoxG5 from here:

Now for the interesting bit: TenFourFox, like Firefox, does not support most plug-ins. Unless you are prone to headaches (in which case don't) you can read about that here:
http://code.google.com/p/tenfourfox/wiki/PluginsNoLongerSupported
But there is a workaround!
Open TenFourFox and type in the address bar: about:config (no spaces) and click return. This gives you a warning that it might harm the application. Ignore that and click on 'I'll be careful, I promise' and you get the config file that you can edit - with great care.
Look/search (scroll down) for: tenfourfox.plugins.enabled
Set it to true. (Double click it to toggle it)
Now close TenFourFox, open it again, and Flash will now work, as it now uses the plug-ins that Safari has stored.
I am using Flash 11.5.502.55 in TenFourFox and it works just fine, including the BBC news site and iPlayer.
