Linux kernel 2.6.7 on sparc.

CONFIG_PCI_USE_VECTOR:

This replaces the current existing IRQ-based index interrupt scheme
with the vector-base index scheme. The advantages of vector base
over IRQ base are listed below:
1) Support MSI implementation.
2) Support future IOxAPIC hotplug

Note that this allows the device drivers to enable MSI, Message
Signaled Interrupt, on all MSI capable device functions detected.
Message Signal Interrupt enables an MSI-capable hardware device to
send an inbound Memory Write on its PCI bus instead of asserting
IRQ signal on device IRQ pin.

If you don't know what to do here, say N.
