Do we want to remove the nvidia suppression?  The bot is currently running on
AMD, but that may not always be the case.

I think we do want to remove them for now. I'm not even sure if they are correct
for nVidia.

How much is left after these suppressions?

There are still a bunch. I defer to Ben for the Font issues. There are also a
couple that may be real.
