http://en.wikipedia.org/wiki/68030According to that, 68030s have an integrated MMU, 68EC030 does not. Since you have a 68030 (according to that chip ID), perhaps SysInfo is looking for an MMU which is not integrated in the CPU but in another chip? I've got no idea if thats true, but Sysinfo on my 68030/40 says the same thing.
