To follow up on this, I've now picked up one of these cards, and just d= id a quick test. Plugged a drive into an on-board socket, booted, made a c= opy of about the first 2MB. Blanked that 2MB out, swapped onto the new card= , booted, made a new copy, swapped back to on-board, booted, and made ano= ther copy. Both copies, and a blank 2MB file, md5sum'ed identically, so it l= ooks like it's safe.
