Yes, DINK lies. At least on all the boards I have, there are 32 MB of memory
even though DINK says there are 64MB (DINK enables an extra memory bank of 32 MB
in the mem ctlr even though the memory doesn't exist). To combat that, I
hard-coded 32MB--yes, an ugly hack--in
arch/ppc/mm/init.c:sandpoint_find_end_of_memory(). If you believe you really
have 64 MB, go ahead and change that routine to report 64MB or whatever you
think is appropriate.
