It looks like your kernel may not be compiled with serial console
support. The best check I know of is to boot the system up with the
stock bios, then interrupt grub, edit the kernel options to include
"console=tty0 console=ttyS0,115200", and then see what happens on your
serial terminal. If that can't be easily done, check your kernel config
file, and make sure serial support is compiled in (no modules, unless
you want to load an initrd), along with serial console, etc, etc.

Also, make sure you allow the kernel some time to load, it does take a
bit. If you're interested in speeding it up, look for Peter Stuge's FILO
IDE Speedup patch in the archives, which is for filo-0.5 (which can be
grabbed with svn co svn://openbios.org/filo/trunk/filo-0.5)

hope this helps
