This may (or may not) be because it tries to mount the first partition and finds it's busy (not surprising as it's the d-i itself) and moves on to the next device rather than next partition. It also seems to assume that subsequent devices are unpartitioned so it tries /dev/sdX but not /dev/sdX1. The good news with my laptop was that putting the firmware on an old SD card out of a camera worked just fine.
