No. Last time this came up rth spoke up and said that link ordering _is_
guaranteed. 

The kernel depends on this in a lot more ways than just initcalls, btw:
all the exception handling etc also depend on the linker properly
preserving ordering of text/data sections.

If the linker ever starts re-orderign things, we'll just either not
upgrade to a broken linker, or we'll require a flag that disables the
re-ordering. 

End of discussion.
