If you want to hardcode a command line, the easiest way to do this is
to modify a few lines in arch/i386/kernel/setup.c:

#if 0
#define COMMAND_LINE ((char *) (PARAM+2048))
#define COMMAND_LINE_SIZE 256
#else
#define COMMAND_LINE_SIZE 256
char COMMAND_LINE[COMMAND_LINE_SIZE] = "console=ttyS0,38400";
#endif

I used this to make a minimal boot floppy with a serial console a
litttle while ago.
