Has anyone got GPU acceleration working in FP10?

Try as I might, I haven't been able to get that damnable green square up. I've got hold of an FP10 FlashDevelop project:

No risk of me having compiled it incorrectly, since I'm simply using the swf included in there. Embedded it with "direct" wmode here:

I'm getting an impressive framerate (hovering close to the target 60fps even though I've got a VM running in the background), and it's doing snazzy Flash 10 stuff, but I'm not seeing a green "GPU acceleration" square in the top-left corner of the swf. Same results if I embed with "gpu" wmode.

My card's almost certainly compatible. I've read that for GPU compositing...

Open GL 2.0 video card with GLSL capabilities required to use this feature.

My ATI Radeon HD 2600 Pro supports OpenGL 2.1 (don't know anything about GLSL though), and certainly there was an HD 2600 or 2600 Pro listed on Adobe's 'compatible cards' list.

I'm definitely using the right player. Tried it in a standalone player I downloaded from the nightly builds minutes ago, plus my browser player (while admittedly no longer has the version number '10'; had to change it to '90' to pass player checks) should suffice, and I've tried similar tests before I hacked it anyway.

To tell you the truth, I'm really running out of ideas. Any help? :(
