Who said so? With libre radeon driver you don't have any 3D acceleration because of the missing binary blob (firmware).

3D acceleration works with ATI cards only if you want to use the binary blob.

Use Intel graphics if you want 3D acceleration to work with truly libre system without binary blobs.

Gnome Shell worked great with Intel Graphics in Gnome 3.0.
