The latest Debian package I could find identified itself as RC2, and
it still seems to have the problem.  (I built it from source).  Was
the bug fixed that recently?

On the plus side, I was able to use the card with the proprietary
nvidia driver and the vga driver, confirming that the problem is in
the nv driver.

BTW, is it possible to build just a driver, or does one need to build
the whole tree?
