I wish I could but the Mobility drivers are "special". You can't use the drivers provided by ATI/AMD unless you modify them (for example, omega drivers but the system becomes unstable). So, I gotta stay with the latest old drivers provided by HP.
ATi question, (ATi HD 4250 Mobile, latest drivers) In ATi Options - for AA - there is Application controlled, 2x, and 4x. Where is the "force off" option?

There is no 'force off' option but 'Application Controlled' means 'off unless the app forces it on' which usually only 3d games do and only if the game is configured by the user to enable it.
Why is HW Accelerated Compositing not working on XP with DX9 and ATI Radeon 9800 (it's DX9 capable)? layers.accelerate-all is set, but about:support shows:

Is GfxInfo spoofing present in beta 7? Does Firefox log anywhere information why it does not enable HW Acceleration? Where in the source are the blacklists? I tried to find them, but couldn't.

DirectX is the June 2010 release, so it is the latest. The driver is 9.1, it is two versions behind the last XP/R9800 driver 9.3, but both 9.2 and 9.3 where buggy (I also tested 9.8 and 10.2 - they were released after the officially last 9.3 and it does not change anything). All gfx and layers settings are defaults. I'll probably try a nightly build, if it won't work I will have to fill a bug report.
Hardware accelerated compositing requires the GPU to support 4096 x 4096 texture size. All older ATI Radeon GPUs only supported 2048 x 2048, it's a hardware limitation and cannot be fixed. Only Radeon X1xxx and later GPUs supports 4k x 4k texture size.
Nvidia GPUs since GeForce 3 supports 4k x 4k texture size. Of course, GeForce 3/4 is DX8 hardware so no hardware accelerated compositing on those, only GeForce FX, 6/7 and up gets hardware acceleration.
