Make sure to enable CONFIG_SERIAL_8250_CONSOLE in your kernel.

added to the kernel which obsoletes the old IDE support. The new ATA
code (libata) exposes all drives under the SCSI subsystem.

FILO has it's own device naming scheme.

I'm sorry the coreboot user experience isn't better for early
adopters like yourself. :\
