i have wrote a patch to qemu to allow it to run with above the 2giga limitations we have now.
i tested it on qemu that used kvm with 14giga of ram, and it was tested at other place with 32giga of ram to the guest ( 32bits, and 64bits).

the patch that i send here, is patch to qemu without kvm,
it include patch to the bochs bios, and patch to the qemu.
part of the patch to qemu fix the typedefs varibles to unsigned long, and it is based on patch i saw at this list
that target sparc.

for some reason the mapping that i do inside qemu with cpu_register_physical_memory dont work, and with this patchs
qemu could not work with more than 3.75giga of ram. ( with kvm it does working... )

this is request for comment, i probbley doing something wrong inside qemu, so anyone have idea how to solve it
please comment :)

anyway for to make it easy to run i put here compiled patched bios.

have fun! :-)
