No you misread the Xorg.0.log: 

[    50.161] (II) Module radeonhd: vendor="AMD GPG"
...
[    51.636] (EE) FATAL: RadeonHD presently does not work with kernel modesetting (KMS).
...
[    50.167] (II) LoadModule: "radeon"
....
[    52.214] (II) UnloadModule: "radeonhd"
...

It's using radeon.

Besides if radeonhd stopped working that would be a regression too, but that's
not what we have here.
