Teardown is just a specification on how to stop processes the most economic way, and is not related to this.
To easily compare between kernels, boot with the kernel option:
init=/bin/bash
(and take "quiet" and "splash" away). Then turn off the machine with "halt -f -p".
My Compaq (with the via chipset) turns off quietly now, I think it has to do with the return to ide/pci/via82cxxx.ko from the ata/pata_via adventure.
