Hi Andrew,

you'll find the whole disassembly attached ... I had to do it with the Windows version of "iasl"
because the Linux version causes a "segmentation fault" on my system :(
I'm a bloody ACPI beginner so I don't really understand the _CRS method (which you'll find at
the end of this posting) - perhaps the ASL code is more useful for you :-)
