Kontron 986LCD-M MP table: 

When any of the onboard network cards are disabled, the bus numbers change 
and thus PCI devices in the riser wouldn't get their interrupts right if a
kernel without ACPI support is booted. This patch dynamically creates the 
correct bus numbers for the firewire and riser card entries
