So what do we do?  It isn't nice to break existing setups.
Maybe mq can be disabled by default (together with Antony's
patch) until fixed drivers will be more widely available?
It's easy to turn off mq by default and turn it on when
needed...

The problem now is that it isn't obvious why your existing
setup breaks when you upgrade.  While when you especially
play with mq, you may look at options available around it...

How difficult it is to fix it in win driver?
