[ltp] thinkpad_acpi max brightness

[Grant Williamson]

Maybe someone on this list knows the answer.

I have a Lenovo T61 7659, intel 965 video card.

When I boot with either rhel 5.3 beta or Fedora 10, the brightness level 
on AC is set to 12.
I know that the t61 has a max brightness level of 15, I can enable this by

echo 0 > /sys/devices/virtual/backlight/acpi_video0/brightness
echo 15 > /sys/devices/virtual/backlight/acpi_video0/brightness

The difference is noticeable from 12 to 15.

My question is, is the "max" level of 12 which is set when I boot, a 
safety net or is this a bug?
