There is a progress notifier feature in <progress.h>. It's not used much at the moment, but it was meant for exactly this:

Generic code calls progress_notifier_call_chain(PROGRESS_BOOT_FALLBACK, "a message");
Board code registers a handler with progress_register_client which prints this to the display
