Only a minor correction - cbfs is the flash image, which so far
doesn't really change at runtime. Stuff added at runtime goes into
"coreboot tables" which is a coreboot-specified data structure which
SeaBIOS finds and uses to know things like the memory map.

When using coreboot+SeaBIOS on real hardware, ACPI tables are built
and put in place by coreboot, and never modified by SeaBIOS AFAIK.
