To compile ati_remote.c.. I ran 'make modules' and it compiled Every module in the src tree.

If i do a make modules_install it will install all those modules. All I want to install is the ati_remote one. Anyone have any idea how I can do this?

Copying the generated .o file from the src to the correct /lib/modules/ tree does not make it work as installed modules are '*.ko' (kernel objects).
