Wouldn't it still be needed if people want to build an ARM kernel that
works on both MSM targets and non-MSM targets?

What about loading the kernel at the next 128MB boundary,
and coming up with a way to use the 126MB before the kernel for
allocation.  That might end up being more invasive, though.
