Thanks to chicken for this tip. He must have really looked through the high resolution image as iFixIt had not marked either of the MSP430 chips. A very good find! He speculates that the MSP430G2402( 16Mhz, 8kB Flash) act as touch controllers. Do you? On the last image, he notice one near the SSD area.
