As I write (in late 2013), most Linux distributions support EFI; in fact, most have supported it for years. The quality of that support varies from one distribution to another, though. In my estimation, the quality of EFI support is best in Fedora and drops off through OpenSUSE, Ubuntu, and Mint, to name a few popular distributions. Some more "do-it-yourself" distributions, such as Gentoo, don't officially support EFI, but their nature makes it easy to add EFI support to them. In fact, it's possible to add EFI support to any Linux distribution: You need to install it (even in BIOS mode) and then install an EFI boot loader on the computer. See my Managing EFI Boot Loaders for Linux page for information on how to do this.

You should check your distribution's feature list to determine if it supports EFI. You should also pay attention to your distribution's support for Secure Boot, particularly if you intend to dual-boot with Windows 8. Note that even distributions that officially support Secure Boot may require that this feature be disabled, since Linux Secure Boot support is often poor or creates complications.
