Hey ramponis,
I'm certainly not in a hurry to get this working and I can wait for your return. After digging into the reference redboot I realized it lacked support for my flash chip, the Atmel AT49BV322A. After I added it to the list of supported chips the flash was finally recognized. Before I could do anything useful I had to erase the whole flash using jtag.
Here is the log of a typical startup and some sample commands:

As the above log show, I could not create a new fis partition since the FIS directory was locked. But why was it locked?
Cheers,
ramcheck
Followup #1: I have since figured out that my memory chip does not support memory unlocking and thus I disabled locking and rebuild redboot. Now I can create partitions:

However, when I try to load and run vmlinux, redboot crashes and goes into gdb. Sic. No more clues at the moment, but I guess I'm making steady progress. 
Followup #2: Yeah, I know. redboot has no support for lzma compression and in order to use gz compression I must add the -d switch. Now everything is fine. I have successfully compiled, flashed and run both redboot and openwrt. 
Here is the result:
