The whole dependancy seems like nonsense to me.
I think

    depends on PCI

is a lot more sensible.

I think the original reasoning was something like this:

If DRM is built-in, then AGP _must_ be built-in or not included at all, modular won't work. If DRM is modular or not built, then AGP may be built- in, modular,
or not built at all.

The "depends on AGP || AGP=n" means that if DRM=y, then AGP=y or AGP=n, and if
DRM=m or DRM=n, then AGP=y or AGP=m or AGP=n.

Yes it's unclear and yes it should probably be documented in a comment somewhere.
