2.5.70-bk10 has some raid fixes, but raid-1 still fails unlike
2.5.70-mm4.

bk10 successfully discovers raid-1 and raid-0 arrays,
but this happens when the kernel tries to mount root:

<lots of ordinary boot messages>
md ... autorun DONE
<this is where I normally get VFS: Mounted root (ext2 filesystem) readonly.
  I got this instead:>
unable to handle kernel paging request at 5a5a5a86

This is a dual celeron with two scsi disks, with
two raid-1 arrays and one raid-0.  The
kernel is compiled with preempt and devfs,
using gcc-3.3
