That "100 people" was just a "supposition", sir :-)

Just 3 or 4 people should be enough if they could get access to the full
specs for the hardware. But that is not the case.

Which are the only ones having full 3D support and capabilities.

The status of the supported capabilities by "radeon" and "radeonhd"
drivers is as follows:
Does not look so good.

No, but at least nvidia clearly says what is their thinking about this.

I agree that Xorg people have done a very good job (by their own) with
But I have to disagree in regards AMD/ATI. It's not a linux-friendly
company and has not released the full specs for their vga cards. Just
some papers. In these days, that's not enough.
