That one should really go into a FAQ somewhere (or rather replace the outdated description in the existing FAQ).

This simple patch allows you to include your DSDT.hex file. I called it "my-dsdt.hex" here, has to be in the directory [linux]/drivers/acpi/, where osl.c is located.

BTW: As this seems to be a common problem, would there be a way to add it as a standard kernel config option?

Have fun,
