I've run into a conundrum. I can use option "3. Escape to loader prompt" at the boot menu and enter either gop set 12 (it's valid) or mode 3 (also valid), and it will change the resolution. But if I add either gop set 12 or mode 3 (tested both, individually) to /boot/loader.rc.local , then nothing happens. It doesn't load those values. I can still go in and change it manually each time, but I'm kind of hoping to have it done automatically, as pointed out in this thread. Any help is greatly appreciated!
