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.

No needs to.
You can still perfectly install other 64bits operating system available and able to run on this old Mac computer.

It's not like Apple keep secret information needed for alternative operating systems to boot on their machines.

Wait!
Oh well. Nevermind.
Let's just buy a new Mac.

It isn't kept secret, they simply don't support it.

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

But they were up to latest MacPro G5.

Well, it can be considered a secret, since what Apple calls "EFI" only remotely complies with the EFI and UEFI specs and keeps doing weird undocumented stuff (such as overwriting kernels after boot) all the time.

Here are some examples :
