I need to do something similar for Xen, so I was curious: I guess the
preferred way for runtime software to fill in values is by *overwriting*
bogus values inserted at compile time?

The other alternative would be for the runtime code to insert new
properties (presumably via memmove()), but overwriting definitely seems
simpler.
