I didn't go back to stock, the box had been running your script with openelec/chromeos dual boot for a long time already, just back to the legacy version that worked previously and now once again. I stuck with GalliomOS this time, since it was what I was live booting off of. But the revert back to the working version enabled dp and hdmi (mirroring) while Gallium was still on the stick, which it wouldn't do under the UEFI, so that you know.
your GalliumOS install on the USB stick was done with the legacy boot firmware, so it would not be expected to boot with the UEFI firmware. If you're moving from legacy to UEFI, you pretty much have to start fresh.
