When I tried a 2.6.1 kernel with CONFIG_PCI_USE_VECTOR, my onboard Ethernet (sis900) produced nothing but watchdog timeouts. It worked fine with the old IRQ routing.
When I looked in /var/log/syslog, I noticed that the Ethernet driver was using a different IRQ, so I suspected the vector routing. I found the following suspicious entries:
Jan 9 20:09:08 jaguar kernel: PCI: PCI BIOS revision 2.10 entry at 0xf11b0, last bus=1 Jan 9 20:09:08 jaguar kernel: PCI: Using configuration type 1 Jan 9 20:09:08 jaguar kernel: mtrr: v2.0 (20020519) Jan 9 20:09:08 jaguar kernel: ACPI: Subsystem revision 20031002 Jan 9 20:09:08 jaguar kernel: IOAPIC[0]: Set PCI routing entry (2-20 -> 0xa9 -> IRQ 20 Mode:1 Active:1) Jan 9 20:09:08 jaguar kernel: ACPI: SCI (IRQ20) allocation failed Jan 9 20:09:08 jaguar kernel: ACPI-0133: *** Error: Unable to install System Control Interrupt Handler, AE_NOT_ACQUIRED Jan 9 20:09:08 jaguar kernel: ACPI: Unable to start the ACPI Interpreter Jan 9 20:09:08 jaguar kernel: Trying to free free IRQ20 Jan 9 20:09:08 jaguar kernel: ACPI: ACPI tables contain no PCI IRQ routing entries Jan 9 20:09:08 jaguar kernel: PCI: Invalid ACPI-PCI IRQ routing table Jan 9 20:09:08 jaguar kernel: PCI: Probing PCI hardware Jan 9 20:09:08 jaguar kernel: PCI: Probing PCI hardware (bus 00) Jan 9 20:09:08 jaguar kernel: Enabling SiS 96x SMBus.

If anyone needs more information (kernel configs, syslog from the non-USE_VECTOR kernel, etc) or if I can help in any way by trying something out, please let me know.
