The coreboot SMI handler already implements that. Remember SMI handlers
stay active even when the OS is loaded.
For security reasons coreboot even locks SMM so that SeaBIOS (or a Linux
kernel module or root process) couldn't just install a new handler.
When experimenting that lock can of course be disabled in the coreboot
source.
