I have been busy with the PiTFT and added the following wiki on github: https://github.com/Junky2008/Buildroot_PiTFT. I still have a problem though. As in the wiki, the screen, touch and X.org server work. I have calibrated the touchscreen and i can move the mousepointer in X. What doesn't work is a "click" I can only move the mouse but not click any items.
Is there a driver I should install to make it work?
OK, I fixed it! apparently I was using an old version of the STMPE kernel module, I will set everything in my wiki! https://github.com/Junky2008/Buildroot_PiTFT
I will mark this answer as "the answer" when I updated my wiki
