Each architecture should have a default configuration.
So you cd into the root of the Linux kernel source, and do for example:
  make ARCH=arm rpc_defconfig
which would place the RiscPC default configuration as the kernel '.config'
file.  You can find the configs in:

If the Efika can boot via tftp (I haven't been following the thread much)
then you place the newly compiled kernel onto your tftp server and boot it
over the network.  This way you leave the original one (on your NAND or
whatever) in tact.  This is how I usually test the new kernels for
This way, if your kernel works then it does -- if not, you can recompile
until you get it right.
