PS - I've tryed the latest 2.6.12-rc3-mm2 kernel, with mdadm v2.0-devel, using the --metadata 1.0 option on the create line, and still get:

mdadm: invalid number of raid devices: 31
As far as I can tell, mdadm just shouldn't give this error when you're using a version 1 superblock. If you disable that check in mdadm.c, I think everything will work. Version 1 superblocks allow something like 2000 disks in an array.
