MSI is broken on this device (actually all PCI/PCI-X devices
in the 57XX family). The interrupt will be asserted as
expected but masking the interrupt does not work. For those
newer 1Gb PCIe devices that do work correctly with MSI, only
a single message is actually supported.

Might be a good thing of someone would work up a man page paragraph to
this effect.
