Hi Remy

The OpenMoko has 128M of memory, so you should be able to fit more
than that.  Having said that by default it places the boot image
in 0x31000000, but it ELF decodes the binary and starts running
at 0x30000000.  This means that you cannot go past 32M.

One quick way may be to modify the simulator to load the initial ELF 
image at a higher address.
