Adding to the e820 is simple.  Just align the madt to 4k:

madt_size = ALIGN(madt_size, PAGE_SIZE);
struct multiple_apic_table *madt = memalign_high(PAGE_SIZE, madt_size);

and then add it to the e820:

add_e820((u64)madt, madt_size, E820_NVS);

It's not strictly necessary to align to 4k, but I think it makes sense
to do that.
