I committed a fix for this a few weeks ago to HAL CVS:
2006-03-10 Richard Hughes <richard hughsie com>
Patch from Paolo Borelli <pborelli katamail com>.
* tools/hal-system-lcd-set-brightness: Sony laptops have a brightness
range from 1..8 not 0..7 and so we need to add 1 before we echo this
brightness value to /proc/acpi/sony/brightness. Fixes g-p-m not setting
the screen to full brightness when set to 100%.
Which I'm guessing isn't included in the HAL version that FC5 shipped in
updates.
I think there are two ways of fixing your problem:
* open a fedora bug saying about the sony fix (i.e. request a patch to
be backported by j5)
* run a never version of HAL -- note there is a CVS rpm available in the
utopia repo if you are feeling brave. Remember if you choose this option
you get to keep both pieces :-)
Hope that helps,
Richard.
