This is not Franck's fault. His patchset does not change behavior if
kernel load address was CKSEG0 and CONFIG_BUILD_ELF64 was not set
(unless you are using gcc 3.x).
Let's clarify things a bit: The Franck's patchset is _not_ fix. It
just tried to avoid undesirable configuration (CKSEG0 kernel with
BUILD_ELF64=y), and clarify some namings.
So I should ask you again, does current git (or 2.6.20-stable) kernel
compiled by binutils-2.17/gcc-4. work for IP32 if you disabled

So I had thought CONFIG_BUILD_ELF64=n worked for IP32...
