You can try setting a different mode at the loader: get to the prompt
(press 9) and play with 'gop list', 'gop set <n>' and 'gop get'. Maybe
you can find a resolution that works fine?

If yes, try loading i915 in /etc/rc.conf, that's the recommended
procedure. Loading i915 too early may blow up booting. You don't need
to load drm explicitly, it's a prerequisite of i915 and will be loaded
