Which script? There's a runtime script, but I want to know about the above
change, which refers to what you're building. (You corrected yourself on
this, but it's still a build-time change)

They were never changed. No modification is made to built modules.

The script that loads them tries to guess which one can be used with this
kernel. If the __iget4 (I think) symbol is versioned the same in 2
kernels, it could lose, and that's a problem, but no patching is done.

No argument.

Let me ask a question more clearly: do your changes preclude building for
all kernels whose sources I have installed (even if I can't do it with a
single invocation of rpm, let's ignore than for the moment, can I at least
build for older kernerls?)
