I am sure where you should put it, but bear in mind that the
command line options and environment are passed to the kernel much as
if it were a user main program (as argc, argv, and envp, in $a0, $a1,
and $a2), by sash or the PROM. You can get things like the console
variable that way (console=g means textport and console=d means
