1,1 - Do I need 2,1 Netkas firmware upgrade to use E5345's?

I'm about to install a 1,1 logic board into my 2,1 Mac Pro case (to replace what I'm pretty sure is a failed logic board). I want to put my Xeon E5345's back in to this machine, but do I need to the Netkas firmware update to bring it up to 2,1 for these CPU's to work?

I'm planning to do the firmware upgrade, but just wondering if I can boot the E5345's with 1,1 firmware and then upgrade the firmware. I have CPUs that come with the 1,1, but I don't want to go through the CPU swap process if I don't have to.

Also, I'm assuming a 1,1 logic board will work in a 2,1 Mac Pro case. From what I understand there shouldn't be any difference other than firmware. Am I wrong?
