- get rid of warning when linux/device.h doesnt exist
        - touch up the Makefile to let the ebuild handle the module details
        - fix support with io remap stuff in newer kernels
        - dont include headers that dont exist in 2.4.x kernels
        - use module_param() for 2.6.x and MODULE_PARM() for all others
        - dont declare all_devices as static since it is exported
        - dont include <linux/config.h> as the build system does it for us
        - in lrmi, map old flag names to new names for versions >= 2.6.26
