Thanks for the information.  It may well be that we should add it to the
blocklist, yes.

That does sound a bit sweeping.  If the intention was to say that the
NVS Quadros have poor performance, I'd be inclined to think that it
could possibly be true.  The NVS series seems to be designed for people
that have no use for graphics performance (e.g. the NVS 295 having about
half the performance of a GF 210).  But I would expect at least some of
the professional Quadros to have acceptable performance for our use.

Then again, we're still trying to figure out which cards have acceptable
performance (and why not).  Not to mention trying to figure out what
counts as "acceptable performance" in the first place.

I expect we will be blocking more low-end cards before the release,
though.

I thought that applied to Mesa 7.10.2 and earlier.  I thought that was
fixed in Mesa 7.10.3.
