I'm sorry to report that it does not. 

I applied the patch, but I had to make a small change to it because the last
chunk did not apply. It seems delayed_slow_work_enqueue() was renamed to
queue_delayed_work() and the patch only seems to add an additional if() before
the call to queue_delayed_work() in drm_helper_hpd_irq_event(), so I modified
the patch accordingly.
I also modified my kernel command-line to include drm_kms_helper.poll=0. 

I had read that the patch might cause X to refuse to start, but I did not
experience this. X started normally on each attempt (I have tried 3x).
Each time the system froze in the same way as before, within a few minutes of
booting.
