I'm facing the same problem.  Any improvements?

I had a look at intel_lvds.c.  I've tried passing something smaller than
intel_lvds_get_max_backlight() to intel_lvds_set_backlight() in
intel_lvds_set_power() but that changed the maximum brightness altogether
(ie. when at maximum brightness according to
backlight/acpi_video0/max_brightness in sysfs, it was not that bright).
So I guess *after* i915 is up a call should be made to restore the default
value.
