Texas Instruments have, as before, published their reference code. (and Google's current reference device, the SGN, is an OMAP4, which also helps considerably).
The Optimus 2X (and its TMoUS brother, the G2x) is a Tegra2, and nVidia has, as always, published a total amount of zero useful lines of code. So I want to ask to nVidia if it's possible the release of all the useful lines of code to make the work on the new OS Android ICS more quicly. There aren't reasons to do not release the driver and we have bought a phone like LG 2x to obtain the best from it, we do not want to wait one year to see ICS on LG 2x because for that time this phone will be old and this is unacceptable for all the peoples that have bought it.
