Could be... although the Beagle ROM seems to be very sensitive to the
precise layout. We might find that the partition must start at sector
63 (but I'm not sure I understand the behaviour yet).
It's not the end of the world if the vfat partition is misaligned,
since this isn't accessed much, and written only occasionally. If we
can have the rootfs partition aligned, that probably brings most of

Could be worth a try.
