What you need to do to incorporate the fix depends on what you're doing
now.  You say you're using 12-RELEASE, but using it how?  Installing
the official image, then adding your own stuff to it?  Or building
world and kernel yourself using the sources from the 12-RELEASE branch?

The bottom line is that you need to rebuild the nxprtc driver with this
patch applied:
