Um, yeah, I just noticed the problem with that patch: half of the numbers in that table are 33 bits, and cause a pile of warnings (not errors, unfortunately!) from gas that scrolled by when I wasn't looking.
Logically, there should be no need for 33-bit values; they should all be reducible modulo the polynomial. But that is going to take a slightly larger change.
