One interesting thing is that with the previous library a Matrox G450 PCI would show up, but only the Hint PCI bridge that it uses.
Thinking that this new library might be able to see through the bridge, I tried it and it causes the machine to reboot before it gets to Workbench.
Removing the card or going back to the old library allows me to get to Workbench.
Not that there is a driver for it, but it was an interesting result that might happen with some other cards.
