Bah! I'm still suffering from jet lag (just came back from Linux-Tage
in Chemnitz).

The next time I compile test a patch for a module, I'll make sure I have
that module's config option set :-( The woe of using localmodconfig. I
should have picked the box with the i915. :-/

Below is the fix. I'll repost a v2 of the original patch.

Sorry about that.
