Where to put xset and kbdrate?

["Michael B Allen" <mba2000@ioplex.com>]

Where sould I put X initialization commands that need to be executed by
root like xset -b and kdbrate -r 24?

I'm using gdm so /etc/X11/gdm/Init/Default looks like a winner but it's
seems specific to gdm. Is there a better place?

Thanks,
Mike
