So let these drivers depend on DMI, for the following gains: * Robustness and safety. Detection of these devices is weak and uses non-standard methods, it should really be limited to Abit boards unless the user explicitly asks otherwise. * Code simplicity. The code is easier to read without ifdefs. * Better build testing coverage. Now there's only one way to build the drivers, so no risk of build failure on exotic systems.
