I hope Paolo will correct me if I misunderstood his suggestion.
Yes, this would work. Alternatively, dumping the flat-view would give you something much simpler: 0000000000000000-000000000009ffff (RW): pc.ram 00000000000a0000-00000000000bffff (RW): vga-lowmem 00000000000c0000-00000000000fffff (R-): pc.ram @ 00000000000c0000 0000000000100000-0000000007ffffff (RW): pc.ram @ 0000000000100000 00000000fd000000-00000000fdffffff (RW): vga.vram 00000000febc0000-00000000febdffff (RW): e1000-mmio 00000000febf0000-00000000febf0fff (RW): vga.mmio 00000000febf0400-00000000febf041f (RW): vga ioports remapped 00000000febf0500-00000000febf0515 (RW): bochs dispi interface 00000000febf0600-00000000febf0607 (RW): qemu extended regs 00000000fec00000-00000000fec00fff (RW): ioapic 00000000fed00000-00000000fed003ff (RW): hpet 00000000fee00000-00000000feefffff (RW): apic-msi 00000000fffc0000-00000000ffffffff (R-): pc.bios This is less information of course, but it may good idea depending on _why_ you're doing that.
