Loongson builds have an ad-hoc cmdline default of "console=ttyS0,115200 root=/dev/hda1". These settings come from a vendor; I remember builds from Lemote branch requiring a "console=tty" override in order to get a working console. At least on Yeeloong, they're particularly useless: there's no external serial port, and the IDE drive is now recognised as /dev/sda.
