When to register termios devices?

I try to register several termios devices in a custom BSP (based on RTEMS 5.1).
I tried to do this in the bsp_start function, but this fails.
My guess is, that it is because too early in the system initialization as the rtems_filesystem_umask is set, so that no device nodes can be added by rtems_termios_device_install.
What would be the right time to do that?
Also, I tried to register my driver initialization function using RTEMS_SYSINIT_ITEM, in several phases, but it seems that the function is never linked into the final binary.
Is there some trick I need to know to make this work?:

It works if I register the additional termios devices in the init task, but I would like to have this added directly in the BSP, not in the user application.

Best regards,
