Turns out that right now, if you try to boot from LVM on ext3 with msdos
partmap, you get a core.img that is slightly too big to fit in the post-MBR
region.  When you're booting from LVM, if it won't fit there you have no
other option, which makes this a big problem.

If you remove _chain from the list, it fits again.  Since _chain can make the
difference between core.img fitting or not fitting, I think it should not be
included unless user requests it.
