[LinuxBIOS] M57SLI interrupt routing

[Torsten Duwe]

irqpoll rulez !-)

With this kernel option I get full performance from glxgears, but the 
interrupts show up under the driver for the only working PCI slot, not the 
primary PCIe! Looking at the board layout I see that this one is exactly 4 
slots further -- maybe Gigabyte did the classic INT rotation over all slots?

I cannot pursue this further right now, this is just a quick note, in case 
someone has a naked board and a multimeter handy :)
