Ok, I took your patches, split them up and fiddled with them a bit.

0004-Add-support-for-axis-inversion.patch
  - self-explanatory, works well btw, at least for relative devices.

0005-Allow-specification-of-Min-Max-for-x-y-overriding-t.patch
  - take config options MinX/MaxX/etc. if given. They override the
    auto-detected values from xorg.conf

0006-Add-touchscreen-support.patch
  - this is the core of your patch, the touchscreen support for BTN_TOUCH.

I got a patch for property support for axis inversion on top of those done as
well.
If we get property support for min/max x and update the ValuatorClassRec
accordingly (I need to find a method to do that without upsetting the server
and all client) then we can do the calibration on-the-fly.
Alternatively, if we find we can't touch the VCR, xf86ScaleAxis should do the
job (that's instead of your TRANFORM macro).

Cheers,
  Peter
