(and will send as soon as clutters are removed and tested further) However, I've got a question on your patch: is it really necessary to patch [arch/arm/kernel/vmlinux.lds.S] file? Without patching that file, it works fine at my system (although it's based on 2.6.36, not 37 rc #) and with that patch, the linker spits an error. If it's necessary to patch [arch/arm/kernel/vmlinux.lds.S], could you please explain a bit about it?
