Have you tried fbtest (CVS module fbtest at www.sf.net/projects/linux-fbdev/)?

Append `console=tty0 console=ttyS0' to the kernel command line, and kernel
messages will appear on both tty0 (fb) and ttyS0 (serial), while console input
will be taken from the last one (ttyS0).

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
