Aha, progress! The packed directive gives attlen of 6 across the
board! Type_sanity test passes now too, so the only failing
regression test is geometry and that is easily dismissed. The
variation is in the last decimal place and probably due to emulated
floating point (ARM has no FPU).
The patch is attached.. it's tiny but seems to be effective.
