The file the device driver needs is an FPGA program file that
- is data that I don't want compiled into the driver wasting space
- will initially be specified when the driver is loaded via rc script
- that can be reloaded by a program to customize it for a particular
   application

I know that this isn't a a typical situation and I have only seen one
other device driver like this.  It is a 1553 driver that creates a
/usr/lib/<module_name> directory for its configuration file.  Is there
a better location?
