I own a T430 and T420. It seems there is not a strong motivation for doing the T430/T530 port. Unlike the T420/T520, the obvious benefit of coreboot is it can replace the sandy bridge CPU with an ivy bridge one. What are the explicit benefits that coreboot can bring to the T430/T530 except opensource/security?

This may not be a concern to you, but to many people it is an issue.
Thinkpads are nice. Their BIOS is not nice.
