x86_64 (64bit), of course.

I get grub-EFI boot menu from the DVD, I choose Fedora,
I get the grub-EFI texts about allocating memory pages for LINUX-EFI, loading VMLINUZ, etc.. 
and then the screen goes blank and everything stops there.

Multiple people have confirmed UEFI boot is broken on Intel 7-series motherboards,
so I believe this is Intel BIOS/firmware bug.
