On platforms with a bootloader that lets you select a kernel,
typically drop in as a new name and select it at boot time. In your
case you may have to rename awy the old kernel and put it in as
/netbsd.

Do you have another system you an mount the SD card in and mount &
rename back on the (unlikely) case something goes wrong? :)
