This program partially works on the Paperwhite, but has some issues that need fixing. The name of the touchscreen device changed from zforce to cyttsp, so I need to change the code that searches for it in the input devices:
I needed to change this:
DT=$(for i in /dev/input/event*;do evtest info $i|grep zforce>$DN&&echo $i&&break;done)
to this:
DT=$(for i in /dev/input/event*;do evtest info $i|grep -w "zforce\|cyttsp">$DN&&echo $i&&break;done)
Also, the eips text output needs to be reformatted. On the K5 and earlier you had 40 lines of 50 characters. But on the Paperwhite, you havee 42 lines of 48 characters. Not only is the line 2 characters narrower, but you can only see the left half of the last character on the line. So practically speaking, in text mode, the new higher resolution eink screen cannot display the rightmost 3 characters of lines that displayed fine on earlier kindles.
Here are the screen dimensions reported by eips:

As you can see, it is 8 bits-per-pixel, just like the K4 and K5. It is not 4bpp as reported in another thread.
