DisplayLink emailed a quick tip that hvsync is automatically restored by any
rendering command.  That, combined with usb_bulk_msg silently failing (I
must be calling it wrong! Last place using it is in modeset .. hmm...), was
the source of the problem.

So now with this checkin, blanking on/off via sysfs is now working at least
on one test system here.

Any problem reports welcome.

Thanks,
Bernie
