sam: really, don't worry about it.  it's part of learning. you've identified
at least two bugs, one spec discrepancy, and more.  this is valuable!

plus, as you've probably noticed, i miss things (takes a couple of
repetitions and i eventually "get it") - for example you had to emphasise
twice about the register bitfields.  i got it in the end.

apparently, it's well-known in the POWER community that everyone dealing
with PowerISA goes through this "adaptation" phase to LE / BE.

now - and this is actually part of the Charter - what i am *not* going
to do is take away the opportunity for you to fix the errors that you
introduced: that's why i put code-comments (that were more lines to
write than if i'd "fixed" the things myself).
