I've made three 'make -j32 buildworlds' using shown version of the swtch.s patch. (It was on the ABIT BP6 based system with two Celerons 366 overclocked to 550 - I know, I know ;-). All three was successfull and the total time (52-54 minutes) was in the same range as on the same system without the patch. But now I use the kernel with the 'sti' and the next instruction swapped. The temperature of idle system changed from ~55 deg. Celsius to ~35 deg. And due the 'make buildworld's it was about the same as without the patch (may be ~5 deg. lower).
