Hello,
You can find enclosed or at
http://arrakin.homedns.org/~nicolas/cputable_750CXe_2.6.14.rc1.diff
A tiny patch which alow to correctly recognized every (let's hope) 750CXe
cpus.
Tested on my system (750 CXe rev 3.1, PVR: 0008 3311).
Feel free to comment and review it.
By the way, a nice 750CXe PVR summary can be found there:
