This all pretty much makes sense, and this is how I solved the problem anyway. However I would argue that (slap me if I'm wrong) , since the videodevX make is calling the kernel make to "make modules": It is the make modules check, in the kernel make file which fails, because it checks the .config file (which doesn't exist on the out of the box distro), maybe it should find out some other way, like by asking the kernel or trying to load a dummy module.

The videodevX-make depends on the kernel config so that the resulting module will be compatible with the kernel. The kernel compile process creates header files from the configuration data that modules depend on to be compiled right. You wouldn't want to load a uniprocessor (the default) compiled module into an SMP kernel, for example. The necessary files for the videodevX make just aren't there on an out-of-box RH install. The version information on module symbols option is causing compile errors with Red Hat's compiler in 7.1. Needs to be turned off in the kernel config. I noticed compile errors from the V4L2 videodev.h in some v4l drivers. The V4L2 videodev.h needs to be fixed to be compatible. In the mean time turn off v4l drivers you don't need in the kernel config. Bill.
