Yes, it works here. This is the kernel which I used to boot my development box at work (including genkernel initramfs for mdraid+luks+lvm): http://dev.gentoo.org/~chithanh/efi/boot/bootx64.efi It has hardcoded crypt_root and real_root via CONFIG_CMDLINE, and initramfs executables are built with -march=bdver2 so this particular file will probably not be useful to many people.
