Well, for one, the SH4 is _not_ that fast of a processor. We're still trying
to make all sorts of optimization shortcuts in the framebuffer and such just
to get it to a point where it can decode MPEG streams in some sane fashion =
..
something like bochs will quite literrally bury the entire system, and with
the added overhead of trying to emulate non-existant instructions, it might
not be feasible at all.

One thing I've always wanted to see was to see a somewhat pluggable emulator
that was capable of emulating an architecture on whatever it happens to be
built one, breaking out architecture emulation into a modular system, though
that's a little different then what you're trying to do.

Plex86 might be another thing to consider, especially if you don't want the
added overhead of X11. Plex86 used SDL as its backend, and thus worked just
fine under framebuffer (with the exception of a few issues). Not sure how
bochs deals with this stuff, but it was X11 specific last time I looked at =
it.
