ok guys,
a little summary from my side:
i've tried the patch from uwe [1] but there are some issues with the baud rate and also the same problem as fred [2] had but with a different output.
the baud problem could be solved with a small workaround: just change to 57600 in minicom but leave 115200 in the bios source. uwe wrote then a second patch (see attachment, works with the lastest svn rev. (remove the old patch before apply the new one)) which fixed the baud problem and other stuff but not the "poweroff" problem.
my first boot log was:

uwe told me to remove all useless hardware during these tests but no difference.
i hope that somebody find a solution to get a working bios for this board.
thats all for now.. i'll keep you up2date if something happens.
