there are two epdc drivers in the kindle gpl releases. the source for the lab126 one is only available in the tarballs you linked (named mxc_epdc_fb_lab126.c).
as for the waveforms, I'm talking about support for the REAGL (sic) waveforms. grep for it in the linux source in the tarballs you linked to.
and e ink did not have a panel that met our requirements, and designed a new one after we talked with them.
edit; just to be clear, we don't use the lab126 driver, it was just an example of there being more drivers for the imx6 generation epdc.
