Yes, I see.

Maybe you could access the same flash memory from the Linux too - using 
either physical or virtual address space, eg. by I/O or memory mapping it.

Yes, I know, but _how_ can I do it? :) In u-boot is very easy but in
Linux I still haven't found a good way to do so.

Another way could be using a dedicated kernel module for the job - eg. 
you compile the graphic support in the module and the when update is 
needed only module can be replaced in the file system leaving kernel 
intact (at least while kernel version does not change).

This is not solve the problem, you still need a compilation stage. I
wish avoiding it. And, on the other hand, you cannot load a kernel
module since you don't mount a root filesystem which is very late
during boot.

Ciao,
