Well, practically all (important) features of nVidia cards are undocumented. 
That's why nouveau people have to RE it basically from scratch. That said, I 
have a feeling that RE is going quite well, they even have some working 3D 
acceleration already. Of course, it is still too early to compare it to the 
closed source driver.

That depends both on the capabilities of the hardware, and on the 
implementation of those capabilities in the radeon(hd) driver.

And yum search says that there is a phoronix-test-suite package in the main 
Fedora repo (this is F12, but I guess it exists for F11 too). I'll try it out 
some day, it would be interesting... :-)

Best, :-)
