Might be a good idea.

Not sure about this, as I don't see much overlap, but it's plausible I
guess.

A 3D driver (at least an OpenGL driver) needs to always keep track of
hardware state anyway, so after a VT switch it can just upload
everything it needs again.

The framebuffer device could offer interfaces for these though?

For very different purposes. Anyway, couldn't the config hierarchy be
changed without moving code around, at least with Kconfig?
