File qemu-intelmac.patch of Package kvm
#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 , ...)
