There are two ways to get that done:
1) re-enable console=pc, and make sure you have gettys enabled, esp.
on your serial port (tty00).
2) Really tell the kernel to not print anything at all. I don't know to
what extent that is supported, some support is available: printf(9)
documents in the aprint_*() functions that you can set a "boothowto"
variable to values like AB_QUIET, AB_VERBOSE and AB_SILENT.
I think the variable can be set from the bootprompt, setting a default in
src/sys/kern/init_main.c would make sense to me. You'll need to change the
C file for that.
In the bootloader, interrupt the countdown and type "boot -q".
The result is not too impressive though:
> boot -q
