Does L4T supports Toradex Colibri Board T20 with their current BSP

I want to use ubuntu on T20 module from Toradex.Please tell are u supporting this T20 Tegra 2 board with IRIS V1.1 base board.I am using Colibri_T20_LinuxImageV2.3_20150320.tar.bz2 image from http://developer1.toradex.com/files/toradex-dev/uploads/media/Colibri/Linux/Images/

Linux for Tegra supports only a development board called Ventana:

Depending on what parts of Ubuntu you want to use, it’s probably still possible to create Ubuntu rootfs for your Colibri T20. Rel-16 doesn’t support the X.Org in the latest Ubuntu’s so it’s not easy to run anything graphical on it.
