Earlier this week, a MacRumors Page 2 article reported that the most recent Apple CHUD Developer tools had made minor UI changes allowing for the possibility of upcoming Quad processor Macs.

The changes were somewhat speculative as the changes are as seen here (old on top, new on bottom).

More evidence pointing specifically to Quad processor support, however, can be seen in the MONster.app seen posted here showing checkboxes for 4 CPUs.

Of even more interest, however, is internal references to a processor called the PPC 970MP.

The 970MP is an unannounced processor which was first referenced in a rumor report from July 2004. The 970MP was described as a dual-core processor with two interconnected microprocessors each with its own 1MB L2 Cache. A few additional details can be found in this 2004 eWeek report.
