PIC was reprogrammed at start but at default values 0x08 for master and 0x70 for slave.

In the Hello64.EXE program, new handle procedures for IRQ0, IRQ1, IRQ12 and Int1B, Int1C have been set. However, old routines are also called. Maybe something "interferes" with the mouse driver. I tested programs with QEMU and Bochs and they work for me. You can use the SD64.EXE debugger and trace the programs.
