I believe (but again, I could be wrong), that with redirection after boot enabled, the BIOS polls the VGA character buffers using a timer interrupt. This mechanism continues to work until Linux switches the CPU to protected mode very early in the kernel boot process - i.e. it works in DOS and the boot loader - and (as has been mentioned already) it relies on things like the boot loader NOT being configured to communicate with the serial port directly themselves. Personally, I normally enable redirection after boot, and disable the native serial coms in grub.
