No, i have AMD k7:

power management:


but i prefer to build kernel for i486 (i686 was giving me troubles on old k6-2 
machine some time ago, and i used variant of this config for LiveCD, 
sometimes for some QEMU tests ... i have real 486 box but it has too litle 
memory , 4mb, for being useful.)

Thanks for figuring  this out, i'll rebuild my kernel for i586 for now.
