Actually I don't think it's fixed. I just tried on 3.8.0 and it doesn't work. Afair Theodore's x230 doesn't use UEFI mode, and afaict everyone else here does boot using “pure” UEFI and no CSM (but a confirmation would help).

My grub-efi doesn't boot when using CSM (indeed) so I can't tell if it'd work on 3.8+ with CSM but I think it's at least related.
