I can't enable hardware accelerated layers on my Radeon 9800 PRO 128 MB in beta 7 or Minefield. I have the newest DirectX package (June 2010) and tried drivers 9.1 and 10.2 (10.2 are latest, 9.1 are older but less buggy). I'm Using fully updated Windows XP 32-bit with SP3. All layers.* and gfx.* settings in about:config are in default state (tried also with a new profile). I tried Vendor ID spoofing in Minefield (to 0), but it changes nothing.

Reproducible: Always

Steps to Reproduce:
1. Install Firefox 4 beta 7 or Minefield
2. Start
3. Open about:support - the result is "GPU Accelerated Windows 0/1"
Actual Results:

It seems the GPU doesn't support 4096x4096 textures:

I would suggest publishing a list of supported devices (and probably some older, but DX9 capable GPUs, with the reason why they do not work) or implement a feature, that would show what tests failed. The Radeon 9800 is a DX9 capable card, that's why I was confused when it didn't work.
Please renom if & when this bug gets confirmed.

It seems like this is confirmed; the only question is whether we should say something in about:support about why d3d is disabled in this case...

The minimum required ATI driver is 10.6. Can you try that on recent Firefox  (7-10)? But you probably still won't get anything.

Yes, the reason for disabling (texture size) should be shown in about:support, I'd vote for that.

Seems bug 673490 could be for that.
Depends on: 673490
