by the way: does it hurt to tune the kernel makefile with

the default, doesn't it speed up the kernel a lot?

x86-64 uses sse/sse2 for parameter passing and float/double arithmetics by default, so these switches are obsolete. However, I guess there is very little floating point arithmetics in the kernel and prefetch optimization isn't done.

3dnow is deprecated, mmx almost useless.

So, it doesn't hurt, it doesn't help.
