The Intel documentation does not list my device [1], but
linuxhw [2] does, and it seems to list a few more bridges
we do not currently cover (3e31, 3ecc, 3e35, 3e0f).  

This might be out-of-scope for this particular patch, but it makes me
wonder - if we know that these other bridges were identified as having the
same issue, would it be prudent to add a quriks for them too?  It might
save some people a headache and such.

Indeed, I was about to do it but the disagreement between the Intel
docs and the linuxhw device list discouraged me. It's confusing that
the most popular SKU in the field (according to linuxhw, which is also
the one I have and the one addressed by this patch) is not in the
official Intel PDF. And what about the numbers that fall in between
the known revisions? Perhaps we could use a mask instead of having
10+ entries?

Then there's also a precedent of adding them one by one in the patches
quoted my Bjorn.

All in all I thought I'd just mention this and let the people familiar
with x86 platforms guide me.

Or maybe we can wait for patches from Paul or Peter to fix the less
popular devices?

Not sure.. I'm happy to produce a patch that adds more entries, or 
for someone else to do it..
