I've finally gottend around to commiting a change for this.  I've
only not saved the t* registers.  v1 is used in syscall(), although
I don't know what the code is really trying to do.

$at is still saved.  It looks safe not to save it, but I chickened
out for now.

Let me know if there are any problems.
