Hi Dan,
I think that is not 64-bit portability bug and the code should be reviewed by Lew Glendenning (who wrote it). I'm sending a copy of the message to Lew and hope he'll check the code ;)
P.S. (for Lew) Lew, I think window->phys in esb2rom_init_one() remains in zero and then sets it to 0xffffffffffc00000 after
window->phys -= 0x400000UL
May be something wrong with word returned at pci_read_config_word()?
