If you decode the board to $C00000 it autoconfigs, right? Did you know that Exec.base gets moved there too? The PAL has FAST memory at that location and it actually makes things run faster.

I wondered about PAL. When they said that the extra meg was "outside the normal expansion range", I figured it might be there, but how the heck can they stop the custom chips in the Amiga from responding. the /OVL signal will disable the custom chip select, but it has to be there quickly, and /OVL is not brought out to the expansion bus. The PAL doesn't need to have internal wiring attached does it?
