Well, ... I was dreaming when I wrote this. I actually remembered that the dynamic linking didn't work, but that was really due to the csu/crt* stuff. You may have noticed that my patches were refering to them, and not to ld.so. ld.so works fine when compiled with "-O3 -fomit-frame-pointer". I rebuild my complete system yesterday, and even linked init dynamically, and everything run wonderfully. Sorry for the misinformation.
