Pokey9000 found a kernel patch for an OMAP3630 Zoom3 devkit, which has a 512MB MCM DDR SDRAM, referencing a part number Hynix H8MBX00U0MER-0EM, giving timings and register values for this part. Looking at the Zoom3 512MB variant memory init code in x-loader shows that there are 2 chip selects of 256MB each. So this is an MCM (stacked chips), 2x256MB each die mDDR.

pokey9000 kernel is 2.6.32-omap1 ( git archive --format=tar --prefix=linux-2.6.32-omap1/ v2.6.32-omap1 | gzip > ../linux-2.6.32-omap1.tar.gz ) stock kernel is v2.6.29-omap1

The audio CODEC is a TI TLV320DAC3100 which has a built in PWM headphone amp, headphone detection, and a mic amp and ADC for a microphone. Unfortunately the headphone jack appears to be a 3-pole TRS style, so there's no mic or control input.
