bugfix realease of the 173 series?

Hi, I have many issues with my FX5200 card on KDE4. As it seems, the bugs are fixed in the 177 series of the driver, but not int the driver for the legacy chipsets (I only bought that card 2 months ago, and it’s already legacy…). I am using the NVIDIA-Linux-x86-173.14.15-pkg1.run installer.

Here’s a screenshot of my dualhead setup which shows the broken panel:

The issue is also described here:

So my question is: am I doomed to live with those bugs, or are there plans to incorporate at least the most important fixes in the legacy driver?

Thanks for any reply!
