This depends. When the bootwrapper version is used then yes, the kernel should 
get changed. This is because the bootwrapper detects the SDRAM size from the 
DDR2 controller and passes it to Linux.

Without bootwrapper no changes are needed, since U-Boot already passes the 
corrected memory size to Linux (totalsize-4k currently).
