I'm pretty sure they don't redefine the meaning of 'eq'....

Why not change the byte-compiler to use 'eq-ignoring-symbol-pos' (or whatever
you want to call it) instead of 'eq'? The byte compiler could do this for every
occurrence of 'eq' in every user macro, as well as in its own code. This should
let ordinary Lisp code run at full speed; only compilation would be slowed down.
