Unfortunately not at the moment, as far as I'm aware of (happy to be proven wrong). It was on the feature design list at an early stage of the dev cycle (so that we could implement things like a multi-touch piano) but time went to the primary use case and no driver work was done exposing this data, as far as I can tell. There are some parameters exposed under /sys/module/zforce/parameters, but nothing like the light level data. Perhaps something to push for in the next cycle?
