d6728f301d7e6e31ba0ee2fa51ed4a24feab8860 is the first bad commit
commit d6728f301d7e6e31ba0ee2fa51ed4a24feab8860

    add serial console support

    Redirect int10 calls to serial console output.
    Parse serial input and queue key events.
    The serial console can work both as primary display
    and in parallel to another vga display (splitmode).

BTW seabios builds under NetBSD-current; the configuration options
will not work, of course.

I don't know what to do after this, though.
