I'm not sure why you address this to me. I don't have any control over lilo. I don't even use it any more (not that grub is immensely better in this area, just different). I'm surprised that LILO cares about the metadata. It should just try to map blocks on a file to blocks on the device. That obviously needs to know something about how md works, but the metadata shouldn't be an issue. If the filesystem in on an md device, then check that it is raid1 and reject if not. If it is, find the underlying devices from GET_DISK_INFO (they might be partitions or whole devices) and possibly add the data_offset found in sysfs is the kernel is new enough to have that entry in sysfs. Add to that various partition mappings and you should have a reliable mapping from file-block to device-block, without needing to know about metadata.
