Thank you for the advice. I filed a bugreport at 
bugzilla.kernel.org and this is how we got the bad dsdt table 
(vista and xp never expirienced this problem). the report is here: 
http://bugzilla.kernel.org/show_bug.cgi?id=10237
As you can see all works well now. But I have to manually insert 
the dsdt in the kernel and recompile it for every kernel. :(

I think the acpi-dev-team did a great job finding and repairing 
this bug but there is nothing else they could do. Inclusion of my 
dsdt in the mainstream kernel is a bad idea because:
1. in the future the table could be repaired but i don't believe 
this.
2. en extra code will be needed to chack for the machine version 
and the bios and apply the patch only on my machine type. :(
3. the kernel shouldn't be a place to put working dsdt tables

Now I'm waiting for another solution to save the 30 min (+ config 
time) for recompilation.
