Nope. After spending a couple of days fruitlessly trying to get my machine to boot
with it enabled, I think we decided it's not worth the pain. Debugging
"hangs instantly and silently on boot" bugs are hard enough when you're in front of the machine,
doing so via bugzilla isn't something I'd wish on my worst enemy.
