I got this confirmation on IRC:

Nov 03 17:06:51 <Lyude> pzanoni: as well: the original testcase I had that was
showing that weird tearing with FBC enabled on hsw doesn't do it anymore on
nightly :)
Nov 03 17:08:29 <pzanoni>       Lyude: nice, thanks! Maybe we could try
reenabling FBC on HSW now...
Nov 03 17:08:44 <Lyude> sounds fine by me

I'm going to close the bug since FBC has been disabled on HSW since a long time
ago. I just wanted the confirmation that we can try to enable it again in the
newest tree now.

(just documenting things for future reference)

Thanks for all the help!
