 *
 * This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
 * some config file that gets updated as new hardware is supported.
 * (And avoiding all runtime comparisons in typical one-choice configs!)
 *
 * NOTE:  some of these controller drivers may not be available yet.
 * Some are available on 2.4 kernels; several are available, but not
