Mac OS X Ars Technica is reporting that certain 64bit Mac models won't be able to run Mountain Lion. The problem is the graphic card drivers; these are still 32bit, and Apple is unwilling to update them to 64bit. A 64bit kernel can't load 32bit drivers, so that's that. Apple has a list of supported models on their Mountain Lion upgrade page, so you can easily check if your computer is capable of running Mountain Lion.

Not since Macs are intel machines, indeed.
Because they can't anymore.

But they were up to latest MacPro G5.

Not since New World Macs too. The New World had no ROM in silicon and making them boot was just down to OpenFirmware and the right bootloader (of which there were several.)
