I think we should be able to match the PCI devices with the information
from the sysfs IB tree.

Although I guess that would require the IB drivers to be loaded to be
able to flash a device.

Or we can fix the order you see here as well as add specifying devices
by the domain, bus, device.

The problem here is that the 2.6 version of libpci returns devices in
reverse order to the 2.4 version which is causing tvflash to create the
list backwards on 2.6.

Since OpenIB is 2.6 only right now, it should be as easy as reversing
the order of the list tvflash constructs.
