OK, I got 1024x768, I'm unstuck.
Check the files in /lib/firmware/edid, I had to copy a set from Armbian.
Edit /boot/efi/extlinux and add your mode to the append line like:
drm_kms_helper.edid_firmware=edid/1024x768.bin video-HDMI-A-1:1024X768
Then update initramfs with update-initramfs -u and reboot.
You should have an edid file to match the video mode you want, and even then not all modes work.
Thanks to mth on #Rock64. If you don't want to get on IRC you can search the logs at http://irc.pine64.uk/
Check dmesg | grep edid if you're having problems..
