August status.
Here's short status: 1. Audio is working, will try to get it into 2.6.36-2.6.37 mainline kernel 2. Battery driver is merged upstream, unfortunately Ben Dooks ingores my patches for some reason, and appropriate rx1950-specific part will not be merged into 2.6.36 :( 3. I got DMA working for s3cmci driver. The problem was in autoreload feature of s3c24xx DMA engine -- MCI doesn't like it for some reason. I rewrote driver to avoid usage of autoreload - and now it's working fine with s3cmci and s3c24xx-i2s drivers, tested on s3c2410 and s3c2442 SoCs
