Well, the wiki says it supports the PPC series MPC74xx, MPC4xx and MPC7xx. The CPU built in the Mac Mini is a MPC7447 (revision B I believe), so I think it should be supported, shouldn't it? The wiki also says the Motorola northbridge MPC107 is supported. According to this page ( http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=MPC107 ) this chipset seems to be only suitable for older CPU up to the MPC7410. I couldn't find any information about the chipset used in the Mac Mini. But as Apple is just an OEM, it should be from Motorola/Freescale as well.
