Folks,
Ive just noticed that, when running FC4, my Pentium-M doesnt have the
SEP flag set,
but it does when running a kernel I built myself.

This is pretty obscure, and I havent seen any problems because of it,
but it is a bit odd.
Can someone(s)
- confirm its absense on 2.6.16-1.2069_FC4 or other
- check their FC-5 /proc/cpuinfo, and report back.
- explain why this is a good thing, or how it might have happened
accidentally ?
