Thanks bfeitell!
I recently updated my pfsense install to a UEFI install to take advantage of the real estate of my 3840x2160 resolution monitor via the console and I had some screen tearing at the bottom which obfuscated the active command prompt. I've been searching for a solution for close to a week and had tried everything from attempting to load vesa.ko and i915kms.ko (for my Intel HD graphics), to trying to get the vidcontrol command to work, to trying to edit /boot/loader.conf with kern.vty=vt, kern.vt.fb.default_mode="<x>x<y>", etc.
This is the only solution that actually worked for me!
Edit: I stand corrected. I was able to change the resolution by interrupting the boot process, but I can't get the setting to load automatically with the /boot/loader.rc.local file.</y></x>
