SD Card driver
From OpenTom
Due to obnoxious licensing rules by the SDCard Association, there is not a single Free Software or Open Source SDCard driver for any kind of hardware.
This is a huge issue, but we're working on it. Expect some news in the future :)
The open alternative is using a MMC Card instead of SDCard. Samsung has released some 2.4.x MMC Card driver source code, unfortunately under a non-GPL license. Also, this driver is old and not integrated with the new generic MMC stack in the kernel. However, a reimplemented MMC driver is also on its way.
