You have to change your running kernel to have support for this option...
it's not a widely used option so it doesn't get compiled in by default.
This is very normal under Linux.  Any time you add a FEATURE to the linux
kernel, you have to reboot for your new kernel to take effect.

Not so if you add a DRIVER which can be compiled as a module, but the
serial console doesn't have a module, presumably because it has to be
there before most of the kernel initializes (in order to display
initialization messages, obviously), so it can't be a module.

Oh well...  Talk to your distribution vendor to have them compile in
support with their stock kernel, and you won't need to reboot...
