Using the latest (2012.12.01) image, I can boot the CD in UEFI mode, `modprobe efivars` and `efibootmgr` work fine and I finished the installation.
However, upon trying to boot it, after a few seconds of init output, the screen turns black and nothing happens.
Motherboard is ASUS M5A97 Evo.
With nomodeset in the kernel parameters, I can boot and get to a command line, but when I try to start X, I get an error message stating that it can't set the mode, so there's less screens than it detected and therefore fails to start.
Without nomodeset, instead of the screen working, as soon as it gets to the part of booting up where it would change the resolution, the screen just violently flashes black and white.
