<pre>After 32.8s (which is when X starts its VT switch), in the kernel we see the
backlight set to 0 (for the modeswitch), then set to 100 (which I presume is
the actual_level being restored), then the kernel sets it to max on the
installation of the fbcon and intel_panel_enable_backlight().
The bug is that intel_panel_enable_backlight() always sets the max value
ignoring the current user value.</pre>
