Note IP27 works fine either way and the code size difference is considerable:
Here are numbers for ip27_defconfig with gcc 4.1.2 and binutils 2.17:

Impressive figures !

However I can't understand why there's a such difference, I'm surely
missing something. AFAIK, we're not doing so many symbol loads in the
kernel ? Maybe this difference is related to ksymall ?

Could you make these 2 kernels available for downloading ?

thanks
