Nope.  Unless you have a new version of DINK that is fixed, it doesn't
set up the memory controller correctly for the RAM above 32MB.  There
should be comments indicating this in
arch/ppc/platforms/sandpoint_setup.c:sandpoint_find_end_of_memory() or
some such (since I don't know what version of MVL you're running).

Try it again with only this on your cmdline: "mem=32M" and see if that
helps.
