This looks like something to keep an eye on..  Matthew
Garrett (the guy who makes peoples laptops work with Linux
and has to deal with EFI & Linux - makes you wonder what
awful thing he did in a past life) writes about a worrying
requirement for Windows 8 logo certification for hardware


# Microsoft requires that machines conforming to the
# Windows 8 logo program and running a client version
# of Windows 8 ship with secure boot enabled. The two
# alternatives here are for Windows to be signed with
# a Microsoft key and for the public part of that key
# to be included with all systems, or alternatively for
# each OEM to include their own key and sign the
# pre-installed versions of Windows. The second approach
# would make it impossible to run boxed copies of Windows
# on Windows logo hardware, and also impossible to install
# new versions of Windows unless your OEM provided a new
# signed copy. The former seems more likely.
# A system that ships with only OEM and Microsoft keys will
# not boot a generic copy of Linux.
