OK, I will include INITRD and see if it the kernel fits. Since the
ramdisk will be loaded from floppy, the floppy driver also need to be
compiled in. Anything else the is required for initrd to work?

Yes, but that would be a different kernel then. Does anyone know what
NICs are most common in oldworld macs (since the nic-drivers must be
compiled in)? I have a de2104x PCI Ethernet in my Performa 5400.
