No; it's quite possible now to boot from beyond the 1024 cylinder mark,
however boot0 does not install in 'packet' mode by default, which means
that you need to manually install/configure it before rebooting after
system installation.
So we don't cleanly install for > 1024 cylinders, but it works with a
little tweaking.
