The 6081 are PCI(-X) only chips, and so cannot be used with PCIe. These older chips had many issues with various things, and most of the errata workarounds required are now in Linux. A few more are coming for 2.6.27, though. The "C0" revision (PCI "Rev.9") is the best of the lot; I wouldn't really use the older ones if I could avoid them, as they do not support PMP hotplug. No FIS-based switching on any 6081, but they all do support PMPs. There is a newer 6042 chip for PCI(-X) slots, which is more or less identical to the 7042 internally and featurewise on Linux.
