Jeez. Crappity, crappity, crap. Embarrassing mistake of the year.

I managed to convince myself that the cable couldn't possibly be
responsible, because we got corruption even when using UDMA-33 (which
protects from cable faults). Somewhere in my logic I obviously lost the
plot, and forgot that I switched DMA off *before* seeing corruption.

Sigh. Ah, I think I see a nice brown bag, in a nice deep hole.

Thank you for gently pointing out the error of my ways ;-)
