From what I can see, it look like they've updated the CPU code in the bios many times.
For my money, and for what it will take to upgrade the bios, I would update it with the original CPU.
Then I would try the new CPU and give it a shot. At this point, you have the new processor and it only takes a few minutes to update the BIOS, so I would try it and see what happens.
Hope this helps,
