Make Gemini boot

This patch consists of all the bits that didn't really impact non-Gemini machines. If you apply all of it, Gemini will boot in the linuxppc_2_4_devel tree.

(Patch attached in gzip'd form due to size.)

Erm, can you fix the current code to work on all of the various gemini boards? I really don't want to bring back the piggyback bits (which are only slightly better than the size/offset hacks). There's nothing wrong w/ adding #ifdef CONFIG_GEMINI in a place or two. In fact, the 'setup_legacy()' call in misc-simple.c is for exactly the same problem the gemini_console_baud_fixup(port) call is for (and since the others are in asm, just change the prototype to take an arg, which they will ignore).
