I think it should protect against any dynamic memory usage during early boot phase too till we reach a point where kernel is aware of BIOS provided memory maps and kernel memory area usage can be controlled with the help of BIOS provided/User defined memory maps. In i386 implementation Eric is alredy taking into account the memory used by bootmem bitmap and initial page tables. I have not looked into x86_64 kernel code whether do I need to make such adjustments. It worked for me so did not bother much. I will look into it.
