Oops!  In 1.6.x, that heuristic hasn't been improve inside the
device probing code.

The relevant function is _probe_proc_partitions() inside linux.c.

Come to think of it, I'm not sure what a good heuristic is.
Basically, we want it to recognize /dev/hda1 as a partition,
but /dev/rd/c0d0 as a device.

Perhaps the regexp /dev/.*[a-z]+[0-9]+[a-z]+[0-9]+ should match

Anyone forsee any problems, or a better solution?
