I just noticed that I forgot to commit a change that adds a compiler
flag that is needed to build working kernels (-mcmodel=medlow).
I've just committed it, you will need to update your tree to get the
change, re-run config, do a 'make clean depend' (using the appropriate
'make' wrapper if needed) and rebuild the kernel.
I've also attached another uncommitted patch that is needed to make
console input using ofw_console work correctly.
Sorry for the breakage.
