Hi there,

Just in case someone is thinking about my problem described above. I 
have fixed it. That was definetlu my fault.
Of course I must have been doing "make menuconfig" inside my Scratchbox 
ARM target within kernel-source-tree but not somewhere else on my i386. 
So the right way is to make any modifications to n770_defconfig inside 
Scratchbox.
Then "dpkg-buildpackage -rfakeroot -uc -us -sa -D" works fine and I get 
new zImage for my Tablet.

Sorry if I wasted someone's time.

BR,
Andrey
