Yes this seems to be the case.
No matter how hard I try to convince sio.c to default to 57600
(I even went as far at setting
static volatile speed_t comdefaultrate = CONSPEED;
so there would be no confusion.
I still end up with random console speed each time.
The boot loader did pick up the speed from /etc/make.conf and
does come up every time at 57600.
