It's really only the Fresco Logic vendor that has this issue. That probably means we should just add the quirk for all their chipsets, but I wanted to give them time to fix the issue (and they were aware of the issue when I talked to them about it). So far, they're on strike two for chipset revisions. If I hear about a third revision that needs this quirk, I'll blacklist MSI/MSI-X for all Fresco Logic chipsets.
