This turns out to be an error on my part, sorry to have you worried. :) I'd accidentally put "console_speed=115200" in loader.conf. With "comconsole_speed=115200" and 9600 baud boot blocks, it works okay, although you don't see any of the boot[12] messages, of course. That's why installing 115200 baud boot blocks is still the better solution for me; my BIOS doesn't have any possibility to set the COM port speeds...
