in-my-not-a-lawyer-opinion, i think introducing GPLv3 code makes the final 
output GPLv3 only if the build includes it.

so if the imported GRUB code stays at GPLv3, and is only for x86, and all of 
the code Graeme is using from u-boot is GPLv2+, then the final result there is 
under GPLv3 only.  but all his GPLv3 code, assuming it's specific to x86, wont 
affect other architectures.
