I doubt it. Register calling conventions for amd64 made the same change=20
for this architecture to look like
	movq	%rsp, %rdi
thus not modifying stack frame layout. Could someone with amd64 current box

Kgdb is more involved. I think that some compatibility stuff needed there,
to be able to step over both old and new kind of frames.
