If you're using the the GCC from stable ("x86") portage (GCC 3.3), then
you should probably use something like:
CFLAGS="-O2 -march=pentium3 -msse2 -pipe"
GCC 3.4 (marked unstable, "~x86") makes it a little simple by adding
a Pentium-M specific architecture type:
CFLAGS="-O2 -march=pentium-m -pipe"
Although, on a laptop you might want to use "-Os" (size optimization)
in place of "-O2", as the disk is a lot slower than desktop machines
and you will probably have longer startup times for programs. I'm not
too sure on that last part, a I don't have a laptop, though. Anyone
else want to take a stab at that? :)
Hope that helps.
