[NTOS]: Forgot to setup an IRQ stack, the kernel was working by magic since in previous incarnations of the ARM port, 0xFFFFyyyy was mapped, so a stack of 0 worked (going downwards).

Browse source 
[NTOS]: Now FreeLDR just calls the KiSystemStartup routine correctly, without any "magic", so fix the code to use a1 instead of a2 (argument 1/2).
