Unless you are working on your own driver for a board with AGP,
the agpgart found in the main tree is of no help on PPC.

I have an implementation for Apple's AGP controller in the
pmac tree, though it's not really clean enough to be merged
upstream yet and requires additional tweaks to the DRM. So far,
I'm not satisfied with DRI stability when using AGP, which is
the main reason why all this stuff isn't pushed upstream.
