You want the v4l-utils package to get ir-keytable.

On Fedora 22 my irw doesn't return anything either, but ir-keytable does and, modulo some edits to my ~mythtv/.lircrc, my MCE remote works in Myth. Hasn't been easy though - between Ubuntu/Gentoo/Fedora differences and lirc vs kernel handling I've done a lot of reading. I still don't know if I've figured through it all yet.
