I know that you wrote it and I know that you're wrong.
Take sparc64_init() for example, which is called from locore.S before
mi_startup():
void
sparc64_init(caddr_t mdp, u_long o1, u_long o2, u_long o3, ofw_vec_t *vec)
{
...
/*
* Initialize the console before printing anything.
*/
cninit();
/*
* Panic is there is no metadata. Most likely the kernel was booted
* directly, instead of through loader(8).
*/
if (mdp == NULL || kmdp == NULL) {
printf("sparc64_init: no loader metadata.\n"
"This probably means you are not using loader(8).\n");
panic("sparc64_init");
}
These printfs work fine.
Come to think of it:
> cd /usr/current/src/sys/
> find . -name "*.[ch]" | xargs grep SI_SUB_CONSOLE
./sys/kernel.h: * The SI_SUB_CONSOLE and SI_SUB_SWAP values represent values used by
./sys/kernel.h: SI_SUB_CONSOLE = 0x0800000, /* console*/

There don't seem to be any SYSINITs that run at SI_SUB_CONSOLE.
