The hardeneddrivers project was hosted at sourceforge.net.
It was not received well by the Linux community so it was

As for as the device driver hardening specification... the idea suffered a
bloody death when it was finally pitched to LKML.  Although there were a
couple of aspects to driver hardening that the community (LKML) did find
interesting, one of those was the idea enabling fault injection testing and
the other creating a HOWTO document to aid driver developers in creating
robust device drivers.

The fault injection fall out spawned http://fault-injection.sf.net, and that
is what I focused on.

So there is the fault-injection project and the driver development
HOWTO guide, which is available at:

http://janitor.kernelnewbies.org/ also has links to some other
driver development papers.
