Thanks again to all who responded and especially to Jari who built an initrd that works. Using Jari's initrd worked right away without any issues. I suppose ubuntu 7.04 uses some weird combinations of compiler/linker options or their package of dietlibc is somehow incompatible but those are just my speculations and I am by no means an expert at this. FYI: I also tried to build the initrd with USEDIETLIBC=0 and that yielded the same result on ubuntu i.e. it didn't work. Many thanks again.
