Custom keyboard layout in tty

I have a custom xkb file to use in gui , german keyboard with hungarian characters. I’m from hungary and I live in Austria.
http://loliboli.hu/data/gerhun/xkb_de_hu.tar.gz (setxkbmap not work in tty ) loadkeys dont list this variant.
I want to convert to tty too. I find ckbcomp maybe this is the solution but not find an example how to do it.
Please give me an advice

Sorry my bad english
