Sigh. Of course not. Reupdated patch (and yes this one compiles):
From: Clark Williams <willi...@redhat.com>

Subject: [PATCH] [rt] i915: bogus warning from i915 when running on PREEMPT_RT
The i915 driver has a 'WARN_ON(!in_interrupt())' in the display
handler, which whines constanly on the RT kernel (since the interrupt
is actually handled in a threaded handler and not actual interrupt
context).
Change the WARN_ON to WARN_ON_NORT
