>Description:

	The VIA VT82C596A in one of my boxes wasn't being configured
	properly by the BIOS, and pci_intr_fixup.c wasn't aware that this
	chip could be handled by the VIA '586 code.  After adding the PCI
	ID to the proper device table, the box is happy:

PCI IRQ Routing Table rev. 1.0 found at 0xfdd70, size 112 bytes (5 entries)
PCI Interrupt Router at 000:07:0 (VIA Technologies VT82C596A (Apollo Pro) PCI-IS
A Bridge)
PCI Exclusive IRQs: 9 10 11
