Thanks for your quick reply :)
- EM100 sounds like a good idea;
It seems to me as if I should wait for the POST card. By reading the Intel specification of the SCH I got the feeling that issuing a 'beep' would be quite easy (well - it took me a day to just understand what Intel tried to say - but that's probably my fault...) as there is a simple buzzer connected to some transistor on the output pin of the SCH. Just configuring the Timer and enabling the output... (clock source seems to be the main clock source...) But that would have been too easy, I guess...
Toggling some GPIO won't be any easier I suppose...
Unfortunately it has to be an Intel Atom as we try to decrease the boot time of our current DataLogger:

I have already been pointed to SageBios, but while project leaders are deciding where to go it's my task to at least try to get the old system running - to be able to estimate the effort and what we can expect as result... I'm pretty sure the Intel Atom board is not the best starting-point - but there was some hope to at least get some debug message out of the board as the chipset seems to have been supported at some point in time...
I'm a little frightened that when I finally get the POST card, it will not output anything...

If Time is of the Essence I don't see how you can do better than getting Sage into the picture. Just my opinion. Deep expertise, smart people, and they're committed to coreboot.
Disclaimer: Not speaking for anyone but me, myself, and I; I've got no financial stake, I just know the people and like them very much :-)
Other than that, again, yeah, beep always sounds easy. I've seen what it takes on some chipsets and it starts to sound less easy over time. Your call.
It's not your fault that you don't understand the docs. The docs suck, always, and they're always missing little things. Just part of the game.
