Title:
  Can't use the lowest brightness setting

Status in Linux:
  In Progress
Status in linux package in Ubuntu:
  Incomplete
Status in linux-source-2.6.22 package in Ubuntu:
  Won't Fix

Bug description:
  Sony TX series and possible many other Sony laptops couldn't use the lowest brightness setting because the default  sony_acpi.c restrict the lowest value to one instead of zero. This could save some energy so the difference between Linux and Windows isn't that high any more. I have always patched the sony_acpi.c on my own but since this module isn't integrated in linux.source anymore it is much more harder without recompiling the whole kernel. If there is any Sony laptop which haven't zero as the lowest value it should be no problem since a bug in /etc/acpi/sonybright.sh sets brightness on the lowest option to 33 (which is out of bound 0-8) instead of zero because of spicctrl which seems to have no impact.
  Of course the /etc/acpi/sonybright.sh of the acpi-support package have to be patched too.
