to be in the laoder as this code can be used very early on.

According to kldstat it uses all of 42KB of memory.

That’s such a trivial amount of memory it’s not even worth mentioning. Even in tiny embedded systems (and who runs tiny embedded systems on x86?) it’s utterly insignificant.

Even if it were significant, how many of the systems without the relevant hardware are ever going to run 13?
