Are there other architectures which have rust based drivers? x86_64
isn't the only architecture which has rust building on it.

The crates are also available in
%output/share/cargo/registry/name-version.crate, although I can't think
of a good way to address them by name without using find-files.

I would personally replace the versions requested by mesa with whatever
version we happen to have in guix so that we don't have to add special
versions just for mesa.
