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.

Congrats. I was loading the kernel into ram via JTAG too.

What module do you have btw ? Basic/Pro/Uber(?) ... I mean one with 64/128/256MB 
RAM ?

Ok, so far I dunno how to correctly (without additional patch) handle those 256megs of ram.
