--- Comment #5 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
hm.

misaligned is tricky.  am just reading POWER 3.0B, book III, 6.5.8 (page 1074),
it says that quad-word (lq, stq) is allowed to raise an "alignment" exception. 
there's several others as well (including when write-through is required or
cacheing is inhibited) however at least if we don't have to deal with 8-byte
misalignment that makes things a *lot* simpler.
