Boot loader could append it to the kernel cmdline for example.

I wouldn't no. Given that this is configuration that the boot loader
is supposed to grok and parse it could just pass it on on the kernel cmdline.

This would also allow boot loaders to provide a menu-drive scheme for
changing kbd layouts, which they then can sanely pass on to the initrd
and OS.
