--- Comment #5 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
storing KAIVB SPR 850 in the Trap Pipeline by *redirecting*
PowerDecoder2 to send OP_MTSPR and OP_MFSPR to that pipeline,
but *only* for SPR=850 (see comment #4)

now that KAIVB is actually in the pipeline responsible for doing
all exceptions (TRAP), the next thing is to actually use it...
