Hmm...
It doesn't works on my machine.

panic at booting at __free_pages_ok() with blow call trace.

[<hex number>] free_all_bootmem_core
[<hex number>] mem_init
[<hex number>] alloc_large_system_hash
[<hex number>] inode_init_early
[<hex number>] start_kernel
[<hex number>] unknown_bootoption

my machine spec
	CPU:   Pentium4 with HT
	MEM:   512M

I will try more investigate.
but I have no time for a while, sorry ;-)


BTW:
when config sparse mem turn on instead discontig mem.
panic at booting at get_pageblock_flags_group() with below call stack.

free_initrd
	free_init_pages
		free_hot_cold_page
