Hi Arnd,

I looked through my fines and found a config that I believe
worked with a derivative of 2.6.35.7.

It has CONFIG_MEMORY_SIZE=0x1e800000.

So what I suspect has happened is that an extra zero has crept into
arch/arm/configs/kota2_defconfig and the intended value is:

CONFIG_MEMORY_SIZE=0x1e000000

Unfortunately I do not have access to a board to test this,
nor am I aware of anyone who does.
