 I haven't been following Intel's datasheets recently.  They usually do
publish all the necessary bits, but they are scattered around, so you
really have to read them all.  Chances are it's mentioned somewhere.  
Besides, I have no access to the PCI Express spec and there may be further
interesting bits there.  I suppose Intel can be queried directly too,
especially by the interested corporate parties.

 I gather with the workarounds disabled affected systems are useless 
anyway, so what's the point?
