To increase the screen brightness on the eMachines M6807 notebook,
pressing <fn><F8> is the only way.
However, pressing <fn><F8> sometimes hangs the computer!
How to solve this problem?

preface: i use asus t9400 laptop, so the things are bit different - anyway
ACPI should manage all these kinda function keys (<Fn>+<F#>) in the same
manner.

do you actually use ACPI in your kernel? i had some troubles with some
versions of kernel (2.4.21 and 2.4.22) when i plug in AC adapter once the
computer has booted up, suddenly the screen becomes dark and it's
impossible to see anything (it's like the backlight lamp just turns off)...
anyway with kernel 2.4.25-gentoo-r3 i've found an ACPI asus buttons support
which can just report to acpid which button has been pressed: you can see
it with

# tail -f /var/log/acpid.events

once this occurs, normally acpid executes /etc/acpid/default.sh with some
parameters (type and code of pressed button, counter) and so you can just
assign it some kinda parameter in order to change brightness of your
screen.

if you use X/KDE there should be some way to manage
gamma/contrast/brightness using dcop, even if i'm sure there should be any
better solution: if you'll find it let me know - when i use older kernels,
as mentioned above, i still have some problems with brightness

Firstly two things: please don't top post; and please remove all
irrelevant parts of the quotations.

Now that's done with, have you even got acpid installed?
$ emerge -s acpid
