amd64 brightness has lowest value after boot

[Rathgeb Markus <maggu2810@web.de>]

Hi!
I have read the mailinglist for over a year and never heard about a
similar problem till last month. But there was no answer given.
If i use a 32 BIT linux the problem DO NOT occur, but for a few month I
have changed again to a 64 bit linux system (I used 64 bit a year before
and there was the same problem).
Everytime after the message "Booting the Kernel" (all versions I
prepared till 2.6.16) the displays brightness changes to the
lowest value, so I have to press the hotkeys till the brightness has an
acceptable value. (this also happens by an ordinary boot without resume.
I notice that because in the attached email the person writes "My
problem is that after resume".)
>From time to time the hotkeys "are confused" (or do not work), too. I
press the key to
increase the value and it go hell, dark, hell, hell, dark etc. (it does
what it want *g*).
Please help me ;-)
and excuse my english.
