I have dumped a memory region which is my understanding what you want
to see. The difference between the good and the bad case is only
the patch
"4fd06960f120e02e9abc802a09f9511c400042a5 Use the new x86 setup code for i386"
I modified arch/i386/kernel/setup.c and dumped 4K of /dev/kmem at the
address of boot_params.
Good case:
