Well, we can move a little bit more code into C, like populating the trampoline page, but I don't the think we can move the rest. Switching to compatibility mode is too low-level to be written in C. And we cannot write the trampoline code in C, as it's in 32-bit mode and we wouldn't be able to generate it from C in a sane manner while building 64-bit kernel (we discussed this before). -- Kirill A.
