It looks as if they did. To quote http://www.lwn.net/1999/features/MindCraft1.0.phtml, which I found to be a well-reasoned summary, though I didn't check their reasoning: Non-issues A few complaints that have been sent to us probably do not figure into the test results. We list them here in the hopes of helping to slow their propagation and improve the quality of information out there. Some complaints have been raised about the test being run on a 4GB server, even though the Linux kernel, in its default form, can only use 960M of that. Patches can be applied to make 2GB available fairly easily. But, in any case, they claim that NT was limited (with the maxmem parameter) to 1G of memory, so this aspect of the test was fair. It would have been more straightforward of them, however, to have simply remove the other 3G from the system.
