The answer to that is a bit complicated :) The kernel people say that
any postprocessing should be done in userspace (in your case sample
averaging and binning) and userspace people say that's too slow and
Try using some tslib filters in tslib.conf first to see if that helps,
and when that is too slow try hacking the kernel driver.
