I thought that the page that was used for the stack on the C64, or at least the C128 (which I had, i.e. the MOS 8502, which is almost identical to the 6502) could be reconfigured. I remember some code that would use stack pushes to achieve faster filling of memory, and that would of course only have been useful if the location of the stack could be changed. But I just can't find anything on the web that confirms this (all resources say the stack was fixed at page 01, I just think that was the default, not really fixed; as I recall it, the zero page location was really fixed, but the stack wasn't).
