For example one discussion says that an ATI Radeon 9600 PRO 4x/8x can
be installed on my system, but that it still may not work unless a plug-in
(AllowOldGPUs - available from Adobe) is installed.
The 9600 Pro will work on a G5 but it does NOT support OpenGL.
The only card which does support OpenGL that can be used on a G5, is the nVidea 7800 GT which has been "Flashed for Mac".
I got mine from AppleMacanix (who have an ebay store) and it works perfectly.

My question: How the heck do I 'Enable' OpenGL Drawing? Or, as Ann wrote, it simply won't work? Anybody know why? thanks...
What Ann said. Photoshop detects your video card—which does NOT support OpenGL 2—and disables OpenGL Drawing instantly.
How the heck do I 'Enable' OpenGL Drawing?
Only in heck, not here on Earth. :D

Other? I'll be sure to review in advance, thanks.
Crashes are a very real possibility. That's why you use it at your own risk.
Does the plug-in need to be in one of the sub folders in the Plug-Ins
directory?
No, as long as it's in the Plug-ins folder, Photoshop can see it.
Just because it is supposed to allow you to use an older card does NOT mean that the card will magically acquire capabilities it does not have.
In many instances, it will have no effect whatsoever.

The question remains as to whether anyone has actually tried this with
the Radeon 9600 Pro
I did — and it doesn't.
I had an almost new 9600 Pro (which works only with the non-OpenGL functions in CS4) but had to buy a Flashed-for-Mac 7800 GT to use the OpenGL features.

And, here's a knowledge base bulletin with solutions to some problems people have reported to Adobe.

If you find an OpenGL Video Card that works with CS4 on a dual processor PPC G5 running OS-X 10.4.11 let me know.
I bought mine from AppleMacanix who sell them via their eBay store:

It has been totally reliable.
