FS#225 - ads7846 reports odd pressure values

using evdev xorg drivers and not the tslib drivers you can receive pressure axis data however there is a problem with the values reported by the ads7846 module and the evdev driver has no calibration property for pressure using xinput test touchscreen you can see the pressure axis ranging from 120-ish for hard press to about 150-170 for light press (low pressure values can be quite erratic) I could possibly hack the evdev module to possibly do something with this odd and narrow range of values, but I rather think looking at the source that the ads7846 module needs some work. is there a git tag that has a known working configuration? as I've had problems getting the kernel to compile the last few times I attempted...
