When I try to install (using the DVD, 64 bit) it hangs when it boots to the installer. I've also had problems with Ubuntu, which also won't boot. What's the deal? Fedora is supposed to support EFI since 11. Am I just missing something?
There are bugs in essentially all EFI implementations to date, but this year's thinkpad violate the specs in some particularly horrible ways. Matthew Garrett has looked into booting Linux on EFI and there was some progress but as far as I know its still not 100% ok.
Its also worth to notice that the Thinkpad bios breaks all advanced trickery with GPT partitions. In theory you should be able to install a GPT-aware bootloader in the legacy MBR area and boot the thinkpad in legacy (non-EFI) mode. But that does not work.
