Correcting S90 RAW images with lensfun/UFRAW (profile and distortion)

I'm trying to correct RAW images under Linux. It appears that UFRAW is the program for this task, and it uses lensfun to correct the barrel distortion.

But lensfun doesn't have the appropriate parameters for correcting the distortion of the S90. Does anybody know where I can find the lensfun parameters for this correction?

Another thing I have been unable to find is a profile for the S90 to correct the color. Without this I am left fiddling with the gamma and linearity settings without any guidance.
