When netbooting a kernel with an initrd or initramfs that makes
the image larger than 8 meg the firmware will kick out the kernel 
and go to the second boot device.  However when the mkzimage 
script is used to create the image instead of 'make zImage' then 
the kernel/initrd will netboot.  So this patch changes boot/zImage.lds
to load the kernel at the same location that the mkzimage would set.

This has been boot tested on POWER5, POWER5+, blades and POWER6
systems successfully.
