Yes - this has been posted in several mac forums. Apple, if they so choose, can provide an upgrade to the firmware that will allow the Core Duo based Mac Pros to run in 64bit. Here's hoping..
I think you are confusing the 32-bit / 64-bit EFI question with CPU architecture. Some older Intel Macs do not have a 64-bit EFI and will not support the 64-bit kernel in SnowLeopard (which you can try out by pressing the keys '6' and '4' while booting).
As default, Snow Leopard runs a 32-bit kernel. There are however not many reasons to run a 64-bit kernel at this stage, since any user application may request and address a true 64-bit address space of its own.
Just so I can understand, bottom line, do you think there will be a way where my iMac 2GHz Intel Core Duo will be able to run Snow Leopard even in 32-kernel mode, and will be able to afford a 64-bit application that 64-bit processing power?
