None of those can return -EIO, but if they did the same principle
applies to them. We would much prefer to disable GEM submission than
disable the driver; the theory being as always if the user can see the
display and the error messages, they can report a bug. If the driver
dies in the middle of loading, it's likely they won't be able to see
anything at all (since we've already kicked out the VGA console and it
is not coming back).
