The standard kernel provides a mechanism to compile a DSDT into the kernel image. It would be nice if Fedora offered a way to load a DSDT without recompiling the kernel, but as far as I know that hasn't been done yet. Use "make menuconfig" or "make xconfig" to set the following options as marked below: Device Drivers --> Generic Driver Options --> [ ] Select only drivers that don't need compile-time external firmware [ ] Prevent firmware from being built Power management options (ACPI, APM) ---> ACPI (Advanced Configuration and Power Interface) Support ---> [*] Include Custom DSDT (/path/to/your/DSDT) Custom DSDT Table file to include Note that the Custom DSDT option only shows up if you deselect the Generic Driver options shown.
