MSI is based on the 2.3 version of the PCI spec for express. Are there
any examples of drivers that use MSI? Where are the writes going: the
IOAPIC or the front side bus? Any pointers would be mucho mucho

I forgot to ask the original poster what they meant by supporting
PCIe. Is there some particular feature that you're looking for like
error reporting, ASPM, hot plug, QoS, etc?
