I just tried it, and yes, Win7 SP1 x64 seems to install and work in UEFI mode.
After win7 x64 installation I verified there is a GPT system partition on the hdd,
and also I used "bcdedit" to verify Windows has booted using bootmgfw.efi and winload.efi.

I opened a thread about it on Intel forums/communities,
where a person from Intel asked if "supported operating system" worked OK..

It seems RHEL is "supported", and RHEL 6.3 server x64 shows the same problem as Fedora,
so that's good in a way. I guess I need to figure out how to open a proper bugreport to Intel.

so in short: Win7 x64 UEFI works, but fedora16/fedora17/rhel63 x64 fail in UEFI mode.
