I see my device is listed here but the above doesn't really use native
backlight because it is still in acpi_osi blacklist. Tried this and I can
see both acpi_video0 and intel_backlight listed under /sys/class/backlight.
Was this the intention?

The acpi_osi blacklist commit (2d4054d84224) has to be reverted, as I
mentioned earlier.  But the revert can be done individually after
merging this patch.  Rafael, could you care?

Done.  Please check the result in linux-pm.git/linux-next.

Thanks,
Rafael
