Sorry to reply to my own post...
This patch to linux-2.6.22/arch/i386/Makefile enables the stable
kernel to build on F9:

Hi,
In regards to:
http://wiki.laptop.org/go/Rebuilding_OLPC_kernel
I gave up on the git head kernel as there seems to be a lot of bugs
there, and tried to build the origin/stable kernel.
I'm running a Fedora 9 (i386) system for doing the build.
I get this set of messages and the kernel fails to build:

I enabled various bluetooth modules and a few additional USB modules
(for bluetooth, serial and wireless interfaces) using make ARCH=i386
gconfig.
Is this a known issue?
