Description of problem:

S3 sleep causes X-display on notebook to remain dim (too dim to properly read)
after resume. FN-key light controls can't be used any longer (no reaction).
Hibernate will not show this effect . it will actually elevate this problem.
Tried several hal-qirks but no result.

If BIOS seleceted light control via light sensor is used situation with
backlight is better, however controls remain unusable after suspend/resume.

Kernel upgrade from 2.6.22.9-91.fc7 to 2.6.23.1-10.fc7 causes keyboard to fail
in many occasions after suspend/resume causing a full stop (no X-server kill is
possible via keyboard).

System uses intel video driver (i810 & 915resol. will not work).

How reproducible:

Backlight dim and unusable FN Keys to control backlight: 100%
Keyboard fail after resume: about 60%

Steps to Reproduce:
1. suspend notebook, either on panel using power manager or using pm-suspend
2. resume notebook (either powerswitch or opening the lid
  
Actual results:

backlight stays dim, dellLcdBrightness will not work setting values, Fn-Keys not
working. Sometimes keyboard frozen (only FN-Esc will put the system to suspend
mode again).

Expected results:

backlight at same level as before suspending or at least controllable.
dellLcdBrightness should be able to control backlight. Fn-Keys are expected to
work. Frozen keyboard should never occur.

Additional info:

Several notebooks show this behavior, even if installed with an i386 F7 system
(eg. running x64_86 is not the problem).
