Was the feature which that commit removed specific to ide devices? That
is, would it have not applied for a drive connected via a USB/Firewire
bridge?

Ideally the kernel partition-scanning code would be fixed to handle these
strange partitions. As a temporary measure, it might be best to print a
warning and not create the incorrect block device.

E.g. user might think "I'll back up this partition"
  dd if=/dev/sdc1 of=partition.bin
or "I'll wipe this partition before disposing of the disk"
  dd if=/dev/zero of=/dev/sdc1.
Neither has the desired effect.
