Thanks for your help.
I just tried the DSDT I downloaded from 
http://bugzilla.kernel.org/show_bug.cgi?id=9915

Now it gets a little bit further when booting with ACPI enabled, but at 
the end it still hangs. :-(

I get several messages "Could not map memory", "AE_NO_MEMORY" and 
"Method parse/execution failed". And then the boot stops.

Is there a way to write these messages somewhere before the system 
stops, so that I could post the exact messages here?

But so far I'm still not able to start the system with ACPI enabled. :-(
