I meant to get around to this, but it seems I had to "fast track" the 
building of my new server, and it necessitated two new hard disks (raid0) 
and a new debian install. And so far, it seems both the raid1 root, and 
raid5 data arrays are properly building and mounting.

Sorry for the noise. If I see it again I'll try and figure it out.

The only hint I might have is that it might have fixed itself when I added 
raid5 to the initramfs modules file. Not sure though.
