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).
