--- Comment #4 from Neil Roberts <neil at linux.intel.com> ---
It looks like there is only one test in Piglit that attempts this. I've made a
patch to make it expect the new behaviour here:

http://patchwork.freedesktop.org/patch/63670/

I also made a patch to completely remove the format restriction in Mesa here:

http://patchwork.freedesktop.org/patch/63672/

Surprisingly this exposed a bug on HSW so it needs an additional patch which I
also posted.

As this patch removes the restriction for all drivers I guess we would need
testing on the other drivers as well before being confident we can land it.
