Check in your factory BIOS, make sure it isn't set up to swap COM 1 and
2? Or even better, check for output from the second serial port? I'm
pretty much out of ideas.

Do you have a POST card? If so, set up a post code at the start of
w83977af_early_serial() so you can make sure LinuxBIOS is in fact making
it that far. Do a post code with outb(0x[code], 0x80);
