This can be adjusted by modifying the coordinates transformation matrix for the touchscreen using xinput. However, other problems arise after doing that.
See this bug for more details:

There are at least three other bugs about this problem registered in launchpad too, but I don't have their numbers right now. However, they've been reported against xorg, without specifying the evdev package.
