I'm a little surprised there's only English on that screen. Perhaps they localize it? That seems potentially flakey to do if the system is in an unstable state.

OSX's Kernel Panic screen has a handful of languages explaining what happened.

EDIT: I suppose they could generate the text/page statically when the OS is installed and every time the locale is changed thereafter. If that is what they do, it's better than what OSX does.

Windows BSOD's have "always" (as long as I can remember) been localised. I would guess your assumption is correct, since it's entirely possible to install Windows without English support (I don't use OSX, but a quick search gave the impression that English is non-removable there).
