Which ALIX board exactly? There are some differences (even various BIOSes).
Any chance you have vga driver in kernel? TinyBIOS emulates VGA a bit,
redirects output to serial port. If at the beginning you are trying both VGA
and serial port, output is doubled. Similar behavior is observed on older
WRAP boards, too.
