SubjectRe: getting configuration info into a driver at load-time

Various drivers do load it after load time (and for one that allows you
to change the configuration without a restart which is usually a good
thing). In some cases driver that need a configuration to do sane things
fails other I/O with an error like EIO until a configuration is
established via ioctl or sysfs or similar.

You can always request_firmware() the tables... bit hackish but works
