If the number in the text above really was represented in hex, it very
clearly is outside the range you show. Assuming it was in fact decimal,
its hex representation being 0x40000000 also makes clear that this is
outside the shown range. But it's also rather strange an address for an
IO-APIC to live at. So in the end I'm only confused.

If with "valid memory" you mean "valid RAM", then clearly the IO-APIC
page(s) shouldn't be touched by this.
