At the moment the only way I know to find the version of EFI/UEFI on Apple hardware is to install rEFIt, bless its EFI folder from command line and restart which will bring up the rEFIt menu. One of its options is an info button which will display information about the machine's EFI/UEFI version. At the moment the only part of UEFI I'm aware that Apple is using is GOP for video, but the primary basis for their firmware is Intel EFI 1.10. And Windows 7 doesn't support it and I have yet to get any Linux distro to boot into a GUI because, as the developers have suggested, they aren't able to extract necessary information from Apple's EFI about the video hardware. They are able to do this with the CSM (the emulated BIOS) but then this is a BIOS based booting, which requires the hybrid MBR hack.
If the most recent hardware from Apple just released does support UEFI 2.x that would be great news indeed. I would then like to believe they will eventually issue UEFI 2.x based firmware for other recently sold hardware.
