Press space at boot for Haiku boot options

On Haiku (the operating system), if you graphics driver isn't working post-boot screen, you can reboot and hit the spacebar early in the boot process to access a menu of options. Go to the "safe mode" options and enable the fallback graphics driver to use the same driver that's (successfully, hopefully) used to display the boot menu.

Note that, as far as I understand, Haiku doesn't have mitigations for Spectre/Meltdown, so I would advise against running any untrusted code on Haiku. Unfortunately, this includes JavaScript in the browser (which I can't find a way to disable).
