Can we leave the legacy support for a while? On PPC32 we don't have
the relocatable kernel support, but we have kdump patches floating
around[1], and they use the `hard-coded values' approach, so far.

I'm not sure if anybody is currently working on a PPC32 kernel
relocation support.. but for sure it will take some time to implement.

Thanks,
