I just realized that "make mrproper" should be executed before the  
"cp /boot/config-2.6.x.x.ydl.1 .config" command. As shown above, what  
you do is delete the .config file that you have just created so that  
the "make menuconfig" step makes one start from scratch.

Anyway, changing the order of "cp" and "make mrproper" commands  
ultimately results in the following error for "make vmlinux"

LD init/built-in.o
LD .tmp_vmlinux1

drivers/built-in.o (.text + 0x60a10): In function`.imsttfb_probe':  
undefined reference to `.nvram_read_byte'
make: *** [.tmp_vmlinux1] Error 1

Any ideas as to where this build error comes from?
