The spufs_coredump_reader array contains the size of the data that will be
returned by the read routine. Currently these are specified as literals, and
though some are obvious, sizeof(u32) == 4, others are not, 69 * 8 == ???
Instead, use sizeof() whatever type is returned by each routine, or in
the case of spufs_mem_read() the #define LS_SIZE.
