I think you are confusing two different things.  The SWI op-code generates 
an exception to the SWI exception handler not the irq exception 
handler.  VICSoftInt is used to generate an IRQ exception which is a 
different beast and will end up being vectored through the VIC as the HW 
interrupts are.
