Even grub's beep (play 480 440 1) goes through the sound-card. So it
seems like the BIOS leaves everything set up working as well.

Please don't get me wrong. I'm not saying the driver does something
wrong, I'm sure it doesn't. I'm just sure that if I could convince it to
behave as if it would have detected the Beep pin everything would work
fine again because it did before...

Attached.

This is from a kernel with both patches applied you sent me.

Nope, no sound. But I guess this wasn't the intention of the patch. Now,
no beep input is registered anymore - which was the intention, I guess.

If you mean it should go through the 5V PC Speaker (i.e. pcspkr) - I
don't have such a thing connected. I always appreciated having volume-
and mute control over the beep at night when you can't get away from
work but don't like to wake up anybody just because command completion
beeps, because you pasted something in the wrong window, or whatever.
