Description of problem:
Controll of brightnes in inverted on this model of ThinkPad (according to 
thinkwiki, its using IdeaPad firmware). Adding more backlight with Fn+End 
causes the brightness go down. Fn+Home vice versa. But the logic of controlling 
backlight is inverted. So the gnome brightness indicator is comming down when 
brightness is increasing and up, when decreasing. Also, when inactive for 
several minutes, powersaving sets brightnes to maximum, as it may think, its 
minimum.

Version-Release number of selected component (if applicable):
up-to-date rawhide
hal-info-20081022-1.fc10.noarch
hal-libs-0.5.12-12.20081027git.fc10.i386
hal-0.5.12-12.20081027git.fc10.i386

How reproducible:
always with enabled X

Steps to Reproduce:
1. press Fn+Home (with arrow marking down direction)
2. brigtness go up

1. on battery, leave the terminal inactive for several minutes with enabled 
power saving by decreasing brightness.
2. look ad the difference on the screen brightness

Actual results:
Backlight controll is inverted

Expected results:
Backlight will work according its logic

Additional info:
# dark screen
[root@fight ~]# echo 13 > /sys/class/backlight/acpi_video1/brightness 
# bright screen
[root@fight ~]# echo 0 > /sys/class/backlight/acpi_video1/brightness
