This makes no sense to me.  When the kernel image is loaded to RAM
starting at address 0x00100000, then ther eis no valid code at address
0x00000000.  So 0x00000000 cannot be a valid entry oint address.  The
entry point address must be somewhare in the range between "load
address" and "load address + size of uncompressed kernel image".

I have no idea.  I didn't know that you were asking for x86...  I'm
not an expert in this area.  I added Simon and Bin to cc: who might be
in a much better position to answer such a question.
