OK, the Beagle Board has a "real" serial port, driven via some GPIO pads and then brought out with a Max232-style chip, so it needs no special drivers once the OMAP's GPIO mux setting is made. So, this serial port works from the VERY start of the boot process, and you see the TI boot ROM ID'ing the processor rev number, the memory chips and so on. This allows you to see the messages from bad SD card formats, and all sorts of similar incompatible boot params and other problems that prevent Linux from booting.
I only know the Beagle Board, so I can't help much beyond that.
