In my experience, that error occurs when trying to use the serial
port when
a) the kernel doesn't have serial support compiled in, or
b) the kernel has serial support via kernel modules and
serial.o hasn't been loaded.
The Dachstein-small kernel in the floppy version of Dachstein
requires the serial.o kernel module to be loaded for serial
support. It's at
http://lrp1.steinkuehler.net/files/kernels/Dachstein-small/modules/misc/
I'm not certain about other LEAF kernels offhand.
