Description of problem:
I was using "acpitool -l 7" successfully before but it no longer works -
expecting due to the current kernel.

Version-Release number of selected component (if applicable):
acpitool-0.5.1-1.fc12.x86_64
kernel-2.6.32.8-58.fc12.x86_64
How reproducible:
Always.
Steps to Reproduce:
acpitool -l 7
Actual results:
Could not open file: /proc/acpi/ibm/brightness for writing.
Expected results:
Brightness set.
Additional info:
# tail -n999 /proc/acpi/video/*/*/brightness
==> /proc/acpi/video/VID1/CRT0/brightness <==
<not supported>
==> /proc/acpi/video/VID1/DVI0/brightness <==
<not supported>
==> /proc/acpi/video/VID1/LCD0/brightness <==
levels: 30 40 50 60 70 80 90 100

# echo 100 >/proc/acpi/video/VID1/LCD0/brightness
works fine
