I have now had a few requests from non native English speakers for the compiled version of the ACPI DSDT that I have created for my laptop. So it is linked here.

Compiled DSDT for BenQ s52 v54

The source copy is located on the acpi website. Please note that this is the upgraded BIOS that you can get from benq version A32.

See the DSDT page from acpi for how to get this into your kernel.

Also thanks to Peter Westwood for his mime-config plugin for wordpress for sorting out the upload of this perculiar file type.
