Eu andei olhando o changelog do kernel 2.6.10 e vi esta msg de Linus Torvald:

<torvalds@ppc970.osdl.org>
Don't use "-march=pentium3" for gcc tuning.

rth tells me that some versions of gcc may end up using the
SSE registers for data movement when you do that.

Use "-march=i686 -mtune=xxxx" instead.

(We do the same thing for march=pentium2/4 too, just for
consistency).

E ai galera ?! Alguma consideração ?!
