I have found something interesting.  No idea what affect this may have if
any.  During the ./configuration there is a check done on /proc/cpuinfo. 
The layout of this file on the ps3 is way different then the layout on
other machines, ie there is no model names or flags line to check against.
 Could this cause any issues?

Thanks
