The los0 image simply initializes the consing pointer to the 2 MB
mark, so you want somewhat more than this configured.

This is the main culprit, most likely. Movitz' bootloader assumes the
1_44 floppy geometry. Probably this should be checked for somehow, not
just ignoring the issue and ending up with loading random junk. Then
again, the loader is confined to 512 bytes, so there's a limit to what
it can do. Anyway, problems that are the related to loading tends to
go away when using the grub loader.
