i do not use Fedora/redhat and do not intent to ever try them again... still, the point is valid
With a pointer to the beginning this would have been a trivial thing to
detect.

IMO it would make sense to support autoassemble for 1.0 superblocks, and
making them the default. The purpose would be to get everyone off 0.9.
However, *any* default is better than 1.1.

As long is autodetect is supported in the kernel, i am willing to upgrade to 1.0 superblocks. BUT i need the autodetect in the kernel, as i refuse to use initrd for production servers.
