Argh ... sorry Takashi. Joey is right. I thought I had tested that,
but apparently not. Indeed, your last patch prevents the backlight
from being turned off, but it also breaks the brightness adjustment
keys at runtime with acpi_osi=Linux. And without that it doesn't
work, anyway, just like before. I'll add some more debug messages ...

Done. No, your patch is not involved. But backing out Takashi's
patch and re-applying confirmed that it's that patch.
