No, it could be anywhere the bootloader chooses to stash it, probably below
1M. 0 is as good a place as any for us: our "bootloader" doesn't live in the
address space, and the kernel copies it somewhere safe almost immediately.
To be honest I'm not sure what normal bootloaders do, but you could record it
somewhere and figure it out...
Cheers,
