I think we simply don't have access to it. Maybe on Grackle machines, we
could try to hack the bridge config (MPC106), but I don't know if Apple's
bandit can generate PCI mem cycles at 0.

Well, weren't some of the early Apple PPC servers running AIX based on
Bandit and using legacy VGA text mode ?
In this case, it may be possible to configure Bandit to open a window to
the ISA memory space...
