No, we load the kernel with -kernel, that's what the first patch does.
But the board is implemented in such way that you can't start without a
bios. If the -bios switch is not present, then the board uses the
default bios. This patch allows to start without a bios:
-kernel <PROGRAM> -bios -

I'll have a look at Andreas' branch and see if it fits our scheme.
