This problem is very hard to solve inside the kernel. The partitions will not be visible until the array is opened *after* it has been created. Making the partitions visible before that would be possible, but would be very easy. I think the best solution is Mike's solution which is to simply open/close the array after it has been assembled. I will make sure this is in the next release of mdadm. Note that you can still access the partitions even though they do not appear in /proc/partitions. Any attempt to access and of them will make them all appear in /proc/partitions. But I understand there is sometimes value in seeing them before accessing them.
