     I'm not happy with Grub2 (I preferred Grub-legacy), but it works 
with the default version of mdadm's superblock. According to the doc, 
Lilo works with the old 0.90 mode only, because the superblock is at the 
end of the partition and it doesn't see it. This position of the 
superblock was also requested by old versions of the kernel to allow 
autodetection. This points to the problem of Lilo: it doesn't seem to be 
actively maintained.
