the text segment can be in flash, data, bss and kernel heap no. more or 
less the same for user application (if you are using XIP but AFAIK it's 
only in uclinux 2.4 (but I may be wrong) which i really bigger).

well the bootloader should copy the data segment to ram, zero bss and 
setup the memory map known to Linux. Have a look at head-arm-atmel.S if 
this is supported or if the whole kernel needs to be in ram.
