Did we try a BLKPG ioctl on it? Definitely we need parted to be able 
to view and manipulate partitions on these types of devices.

Whether we go as far as automatically notifying the kernel of changes 
(by whatever means is appropriate for the type of device), I am less 
sure - it seems like a "nice to have", but there are some nasty 
complications to deal with (e.g. differing conventions for naming 
partitions on these devices exist).
