How can FreeBSD work with keyboard on a dead southbridge where other systems fail?

So, here is the story: I have a laptop Acer Aspire 5100, which has a
dead southbridge. In any operating system it predictibly results in
non-working audio, usb, keyboard and touchpad. I tried Windows XP,
Windows 7, Linux and FreeDOS. They all work ok on it except this minor
stuff. I also obvioulsy can't access BIOS since keyboard is dead. And if
I install FreeBSD on it ofcouse I cant skip that autoboot delay with the
boot menu. But if system boots - the keyboards suddenly works like a
charm, and that makes my laptop totally usable and fine (for example to
set up ethrenet switches using cardbus serial adapter). That's a
miracle! Or is it?
So the question is: what makes FreeBSD so different? How does it work
with the keyboard and why no other OS uses this method then?
P.S. I even made the video about this situation and it has an image of
this laptop's motherboard if needed. Here it is:
