current kernels do not boot, they hang after 'returning from prom_init'
gcc4.1 and mainline miscompile arch/powerpc/mm/hash_utils_64.c.
Taking the object file from a gcc4.0 compiled tree fixes booting.
gcc-mainline r108000 binutils-mainline -> fails
gcc-4_0-branch r107977 binutils-mainline -> works
gcc-4_1-branch r106530 (+patch r106693 from bug #24644) binutils-mainline
2005-11-05 -> fails
