I'm pretty sure this is referring to pre-production hardware and
unfortunately this erratum is left in the PRM due to the way the
documentation is generated. I've run the piglit tests on an IvyBridge
laptop and they do all pass. The piglit tests include tests for all
three of those formats and there is a pretty exhaustive one for the two
half-float formats.

Thanks for taking a look at it.
