This is what I expected.  Looking quickly over the prep_* files in
arch/ppc/platform confirms that the MVME2100 is not supported by these
files.  As an aside, mkbugboot is only needed to put an image into flash
and boot it. mkprep is used for hd(/cd?), floppy and network.

Now, a quick googling for Linux and MVME2100 gives this very old, but
mostly sufficient patch:
http://www.aps.anl.gov/asd/people/anj/mvme2100.patch.gz
Since you have the hardware, from here it should be not too hard, using
the LoPEC as an example, port the code in that patch to 2.4 and 2.6 (if
you do a patch vs 2.6 we can get that support into kernel.org, if you're
willing to try and keep the platform working).
