RH 7.1 out of the box does not have a .config in the kernel directory. Make xconfig will not know what options had been used to compile the running kernel. Modules must be compiled with the same compile options and same compiler version as the kernel they will be loaded into. Therefore, if you want to compile a module for RH 7.1, you must recompile the kernel and the modules, install the new kernel and modules, and finally re-boot with the new kernel. Change the EXTRAVERSION in the Makefile first so you don't clobber your RH kernel, just in case you make a mistake. That's for modules in the kernel tree. If you have source for a module separate from the kernel tree (such as videodevX), you need to build and boot your own kernel/modules before building and installing the external module. Going through all the options on make xconfig is really painful. Fortunately, RH provides some example configurations in the configs sub-directory. Copy one of those to the main kernel source directory as the file ".config", then do make xconfig. Once you've got your own kernel running, you can build and install modules to your heart's content without rebooting. Each time you make a new kernel you should recompile your modules. Bill.
