I'd prefer to use the "file" method - but I wont hold up your patch
for it.  If the host part of your patch is committed to qemu, I'll
commit the SeaBIOS part.

I find this struct to be easily confused with 'struct e820entry' in
memmap.h.  Both code should use the same struct, or the new struct
should clearly indicate it's for qemu (eg, "qemu_e820_entry").
