Update for this week.

My understanding is that the issue truly affects fi-ivb-3520m and fi-snb-2520m
on the CI, but not fi-hsw-4770.  

The fi-hsw-4770 should indeed skip every time since, according to the Hardware
information page, it has VGA attached, and the test requires it to be
disconnected:

 igt_skip_on(vga_connector->connection == DRM_MODE_CONNECTED);

On my HSW, I can hit the issue sometimes with VGA disconnected, but I wasn't
lucky enough to catch it after setting debug information.  I'm checking the
kernel for spots where it might be racing and reporting bad information about
connectors.  Tips are appreciated.
