Indeed - that was the problem - I greped for the size (in hex and dec)
but _not_ for a formular ;-)

Well, probably I can - changing the size to the real size (which is 32MB
instead of 128) - u-boot boots up to the prompt. Probably some memory
test addressed memory above 32MB. So it works now.
Regarding the version of gcc, I use
ppc_405-gcc (GCC) 3.3.1 (MontaVista 3.3.1- 2003-12-24)

Thanks for your helpfull hint!
