Btw, can you repost that one as a new email (and cc keithp too)? I
think it got hidden in the other thread by different subject line.
Jesse, did you take a look at that one? It was in the thread with a
subject like "[PATCH] fix backlight brightness on intel LVDS panel

Search for

but intel_panel_enable_backlight() is called at resume. With the
effect that if the brightness was ever changed after screen
blanking, the wrong brightness gets restored at resume time.
