It's a problem with the bios and the way it handles the PCI bus. I have the same problem, and I fixed it by playing around with the bios settings for IRQ. Check your bios and try setting some IRQ's to Legacy ISA rather than PnP/PCI. I believe this reserves a specific IRQ for the SB Live card allowing it to work. I'm not sure of why exactly the bios does this, does anyone know for sure?
