.09? I assume you mean .07?
Then I'm guessing you're talking about the version in the portstree?
Nvidia doesn't maintain the port, only the driver/installer found here.
The version numbering scheme of the nvidia-driver itself seems to have changed again and it throws a monkey wrench in the port's selection of patches to maintain the older versions too.
I'm sure he (the port maintainer) is working on it. It isn't as simple as changing a version number and some checksums unfortunately. I know, tried that myself
