--- Comment #1 from Alex Deucher <alexdeucher@gmail.com> ---
IIRC, get-edid doesn't actually probe any i2c buses, it uses vm86 to do vbe
calls to the vbios. vbe will only provide the edid for whatever monitor it
happened to probe at boot and likely won't work correctly once a real driver is
loaded. It's also not multi-head aware so if you have multiple monitors
attached or are using a different display than what was available at boot it
probably won't work.
