Summary: Trap always *puts* you in Super mode

You're close here, Fred.  A trap always puts you in Super mode, so you
will have the status register on the stack.  Since you're in Super
mode, you're automagically using the ssp (as a7 or sp).  That's why
the function code is at 6(sp).  I don't know why the cmpi is changing
the data it looks at!
