system fails to resume in Hardy with non-free nvidia driver

Binary package hint: hal

On a system with Hardy and the non-free nvidia driver, initiate a suspend/resume cycle. On my system, it fails to resume from suspend. In Edgy and Feisty, in order to make things work I edited the /etc/defaults/acpi-support to disallow vbetool and friends from touching the video chipset, but those changes are not being imported by the new pm-utils framework.
