Ah, make uImage you say... I tried both with codesourcery and
arm-linux-gnueabi from emdebian.org and I can see now a small (around
1.3 MB) uImage file in arch/arm/boot!
Maybe my mistake was that I was doing:
make ... all
make ... modules_install install
to get the kernel, modules, then vmlinuz and System.map placed in /boot.
That probably deploys the wrong image file.
I guess I can try to flash SS4000-E's mtd with a non-modular uImage
kernel and get away with not doing initrd.
Still to check that though...

Maciej
