Well, booting the factory provided kernel would be great and that
would be a reason to preserve the 5032.
But the fact is that's not possible for now. Archos has added some
tweaks to their bootloader and kernel so they write board specific
information in the boot sector and the bootloader passes it to the
kernel.
To be able to boot their kernel this "feature_tags" should be
implemented in barebox.
For more information see:

Vicente.
