I changed something here a few weeks ago. The idea was to avoid listing partitions of size 0 but do list full devices, regardless of size. Especially in case of removable media that is useful. For example, a blockdev --rereadpt /dev/sda might show that there is something there now. Will look at what might cause your strange numbers. Unfortunately recent 2.5 kernels do not boot for me.
