partitions on software raid revisited - more questions

Hallo there!

Some time ago there was a discussion about software raid and the new 
partitionability feature.

Since I upgraded to kernel 2.6.6-rc3 with libata I now have this feature 
inside the "native" kernel and want to try it out.

The dynamically allocated major number seems to be 254 (according to 
/proc/devices). This, however, could change when adding more dynamically 
allocating drivers. Am I right?

My main problem at this moment is how I can access the devices via 
/dev/something.

There should be something like /dev/md/d1p2 for example. This is not 
existing per se on a Debian woody system (no wonder). How can I make 
these entries, since mknod wants to have a major number to make these 
devices? Do I have to use a newer mknod? Or does my kernel lack some 
functionality? Perhaps then I wouldn´t need nodes at all?

One other thing: I put together a raid5 out of four identical sata hdds 
(dev/sda and so on), then partitioned it (md9) with fdisk. fdisk -l of 
the drives shows me no entries for sdb and sdc, however the following 
(similar for sda and sdd):

rossweisse:/# fdisk -l /dev/sdd

Disk /dev/sdd: 255 heads, 63 sectors, 19457 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/sdd1             1        98    786434   83  Linux
Partition 1 does not end on cylinder boundary:
     phys=(1023, 1, 4) should be (1023, 254, 63)
/dev/sdd2            98     38950 312074260   83  Linux
Partition 2 does not end on cylinder boundary:
     phys=(1023, 1, 4) should be (1023, 254, 63)
/dev/sdd3         38950     58372 156011752   83  Linux
Partition 3 does not end on cylinder boundary:
     phys=(1023, 1, 4) should be (1023, 254, 63)

Is this normal?

Thanks for any help, Norman.
