Unfortunately, no luck here. I tried building both with and without the
patch. Without the patch, brltty works as it always has. With the patch,
my display isn't detected and brltty starts chewing CPU crazily after a
few seconds. Debug output isn't much help; the last line of text relates
to initialising the screen driver.
