Temporary fix to bypass mmc card discovery problem2011.09
The current 3.0 Snowball Android kernel has problem discovering the mmc card - the probing process seems overly long. Disabling the emmc and probing the mmc earlier in the boot process seems to help yielding a booting system. This should be reverted when the real solution is found.
