..
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.
Cheers
