    Was wondering if anyone has had any issues with Lion running a 4.1 that was flashed to a 5.1 with a different CPU installed?

    Thinking of going this route myself but was a little hesitant to see how it would react with Lion.

    It's working great for me but at one point I screwed something up and wanted to install again - I tried booting to the Lion "Recovery Console" and although it booted into it fine, when I choose "Reinstall OSX" from there it told me my machine was incorrect for the OS. :) I just went back and booted from the DVD I had burned of the install image and did another fresh install and it had no problem with that.

    Interesting enough, when I run System Information on the first window is says "Mac Pro Early 2009" for me, but if I then run System Report is shows me as a 5.1 and not a 4.1
