HalAssignSlotResources() Call May Not Assign Resources

On i840 symmetric multiprocessor (SMP) computers with multiple PCI buses and AGP ports, a HalAssignSlotResources call may not assign resources for a Universal Host Controller Interface (UHCI) USB host controller.

The call does not work because the MPS hardware abstraction layer (HAL) does not search for PCI interrupt routings beyond #INTA.
