Does FC3 issue halt to Athlon XP cpus when idle?

[Steve Bergman]

I know that at one time the kernel did not issue a halt instruction to 
athlon cpus due to some sort of bug that caused some athlons not to wake 
up again.

Is this still true on, e.g., an Athlon XP 2100+ with the current FC3 kernel?

Thanks,
Steve
