Yeah, that's the "safe" patch which stops us executing the codepath that
breaks, but also means I don't get display switch events. Having it set
to 1 means executing BIOS code that's likely to interfere with the rest
of the system, so a crash isn't surprising. But a setting of 0 *should*
be safe, and I'm quite confused as to why it's exploding.
