That's exactly what the patch does - but if there is already a way to set the
IRQ to 0, I would of course prefer to use that.


It seems I haven't found the trick you're using - could you please tell me how
you set the IRQ to 0?  I can't change it in the BIOS, so I have to do it at
the kernel level at the latest.



Thanks
