Sorry I'm late. I finally managed to get a working serial console by wiring the PL2303 through a logic level converter. The spec said it would support both voltages, but only the 5V pins are connected on the one I got.
If it wasn't for thagrol the pi would've been fried already. Special thanks to you for warning me.
Also I apologise for any confusion about the problem. All I'm trying to do is have the boot process entirely over serial. Just having the video output there doesn't bother me. Thing is, when I power up the computer I have to cross my fingers and hope for the best. Once I tuck the computer neatly behind furniture there's nothing going into it except for power, ethernet and uart.
OpenBSD on arm64 safely defaults to serial console since it can't rely on there being a framebuffer at all. Now all that's left is figuring out how to get any initial messages and bootstrap loader to appear on the serial console as well. Should anything go wrong I could force an unexpected reboot and perform recovery with the ramdisk kernel.
USB mass storage boot would be a nice bonus, if at all possible.
Thank you all for your kind help.
