I've just installed cudadriver_2.2_vista_64_185.85_general.exe from nVidia's website, and rebooted as instructed. I started BOINC and I got the log message:

10/05/2009 12:03:49 CUDA device: GeForce 9800 GT (driver version 18585, CUDA version 1.1, 512MB, est. 60GFLOPS)

Now since I've just updated to 2.2, shouldn't it be reporting that version instead of 1.1?

On that line, BOINC is reporting the 'compute capability' of your hardware, rather than anything to do with software. The definition is a bit hard to come by, but it's in Appendix A of the CUDA programmer's guide - try http://developer.download.nvidia.com/compute/cuda/2_2/toolkit/docs/NVIDIA_CUDA_Programming_Guide_2.2.pdf if you're interested. Appendix A starts on page 99 according to the document page numbering, or page 107 according to Acrobat Reader.
