You also need to move the call to smp_boot_cpus() below the 
clear_bit(...) line in smp_init().  Without it, my Wildfire doesn't get 
past the while(wait_init_idle) loop - seems all of the CPUs have already 
done their work before the mask is set.  Besides, it's the right place 
for it anyway.  I'd generate a patch, but my system is bogged down in a 
benchmark for the next couple of hours.  If someone says so, I'll 
generate the patch after that...
