I wasn't able to get a linux kernel to ouput stuff with that console command,
however, I did tell the box to redirect the BIOS console to serial, and that
showed stuff.

[Standard BIOS stuff / EFI screen]

The elilo.conf part for Linux-2.6.10 is:

image=/boot/vmlinuz-2.6.10-1-mckinley
        label=Linux-2.6.10
        root=/dev/sda2
        read-only
        initrd=/boot/initrd.img-2.6.10-1-mckinley

The kernel was installed via aptitude.
