ATI has had hardware acceleration on the Rage Pro chips with some of their
beta drivers and I believe the current release drivers do support it now.
It's a bit tricky though because they don't support hardware acceleration at
all color resolutions with the Rage Pro. For example, in the past, only
16bit modes supported hardware OpenGL acceleration. Currently, with the
Rage 128 and Radeon chips, I believe they support it in 32bit mode as well,
possibly in all supported color modes, but I am not certain of this. You
should always read the release notes with the driver for this info.
Hope that helps.
