0x20 (COM_FORCECONSOLE) isn't enough, you have to use 0x30
(COM_FORCECONSOLE | COM_CONSOLE).  COM_FORCECONSOLE is ignored if
COM_CONSOLE isn't set.

There's no need to recompile anything; the third-stage loader will
automatically use the serial console if the second-stage loader does
(i.e. /boot.config contains -h).  The reason why there are two
versions of the first-stage loader is that space constraints preclude
supporting both VGA and serial in the same code.  The second- and
third-stage loaders have no such constraints.
