Calling setxkbmap when starting X

[Ivan "Rambius" Ivanov]

Hello,

I am from Bulgaria and I use Bulgarian language on my FreeBSD machine.
I use the following command

$ setxkbmap -model pc105 -layout "us,bg" -variant ",phonetic" -option
"grp:alt_shift_toggle"

to enable both Bulgarian and English. However, I call this command
every time I log in KDE. Is it possible to invoke it automatically
when X is started?

Thank you in advance for your answers.

Regards
Ivan
