#qemu-only -> submit upstream qemu, but improve first: 
# undo rather hacky pci_enabled -> model > MODEL_ISA changes 
# and replace checks wether to enable newer emulated Mac hardware 
# depending in the bits in a bitfield which is passed pc_init1() 
# like this: pc_init1(.... , ISA, ...) 
#            pc_init1(.... , PCI | IOAPIC | PIIX, ..... 
#            pc_init1(.... , PCI | ICH6, LPC, SMC , ...)
