The driver is also available as a module ( = code which can be
inserted and removed from the running kernel whenever you want). The
module will be called rivafb.o. If you want to compile it as a
module will be called tridentfb.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
