CCing linux arm kernel.

Try one more thing ... check if the kernel with my config forces command line and 
if so, check if there's a mem= option. If it's missing, add mem=128M at 0xa0000000, 
for some reason, I recently had issues with passing kernel params from 
bootloader.

I also had issues with 256MB module, dunno if it's your case. FTTB, use only 
128MB until it's solved. It's work in progress.
