You definitely have the kernel-module-input package created - right? Because 
it's an RRECOMMENDS, that package can actually not be produced by the kernel 
(i.e. because the corresponding config option is 'y' or 'n' instead of 'm').

Another much less likely possibility is that you have BAD_RECOMMENDATIONS set 
to include kernel-module-input. bitbake -e | grep ^BAD_RECOMMENDATIONS will 
tell you if that is the case.

Cheers,
Paul
