Please try this patch:
http://people.freebsd.org/~avg/acpi_cpu_notify.2.diff

I should have committed this earlier, but the fact that we were not getting much
problems when updating resources in place lead me to believe that we would not
get more problems when first deleting and then re-creating resources.

If the patch works OK, I'll commit it tomorrow.
