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.

I'm sure the guys in the OSx86 community will have drivers for those gfx cards in no time, or maybe already have them!

Yeah, I don't think this is that big of a deal. My business-class HP Desktop from 2009 is technically obsolete if I want to run 64-bit Windows. HP simply didn't support this machine in anything other than a 32-bit environment, and that is the official stance posted by an employee in their forums. I found that out when I upgraded to >4GB of RAM and couldn't find amd64 Windows drivers for basic functionality like ethernet and the chipset. Getting everything to work involved a lot of trial and error, downloading zip files from Taiwanese chipset manufacturer web sites and testing them out one by one until I found something that worked. What a nightmare.
