modified netboot.img for ppc

[GABRIEL KAPITANY <gkapitany rogers com>]

Hi,

I'd like to modify the default netboot.img for PPC and
I'd like to append some parameters to the kernel:
ks=.. ksdevice=..

What I'd like to achieve is an unattended install
similar to pxe, using a kickstart file.

The tool used is mkzimage(ld) but I don't know how can
I do that, hardcode in the kernel?

Thanks,
Gabriel
