What about this "beautiful" series? It produces

memory
0000000000000000-000fffffffffffff (prio 0, RW): system
  [...]
  0000000060000000-00000000ffdfffff (prio 0, RW): alias pci-hole @pci
  0000000060000000-00000000ffdfffff
  [...]
  00000000ffe00000-00000000ffffffff (prio 0, R-): system.flash

and I can run OVMF with it. It also stays within i386/pc.

Re 2/2, note that "below_4g_mem_size" never exceeds 0xe0000000 in
pc_init1(), so the subtraction is safe.

Thanks
Laszlo

  i386/pc: propagate flash size from pc_system_flash_init() to
    pc_init1()
  i386/pc_piix: the pci-hole should end where the system flash starts
