My last two systems (desktops, I don't even have a working notebook right now, waiting for Broadwell) used Asrock and ASUS boards with EFI implementations that worked pretty well out of the box under Linux. One runs Suse 13.1, the other runs Arch. They both have their bugs - the Asrock system wipes the EFI boot table every firmware update, and the ASUS one can only have one entry in the EFI boot table, and neither has a working EFI shell - but I did my research to know they worked.
