Welcome to the g2root arm foreign/hostile kernel exploration toolkit.
syntax:
CROSS_COMPILE=/opt/arm-2008q3/bin/arm-none-eabi- ARCH=arm make KDIR=[KERNEL SOURCE FROM WIKI] [clean|DOSTUFF=0|DOSTUFF=1]
Building the toolkit
You'll need an ARM toolchain. The following assumes you're using the
CodeSourcery tools installed to /opt/arm-2008q3; otherwise, change the
CROSS_COMPILE variable.
$ git clone git://codeaurora.org/kernel/experimental.git kernel-source
$ git clone git://gist.github.com/619505.git module-source
$ cd kernel-source && git checkout origin/aosp/android-msm-2.6.32-7x30-wip
& # The follow commands may need to be run with CROSS_COMPILE=/opt/arm-2008q3/b
$ ARCH=arm make surf7x30_defconfig
$ ARCH=arm make oldconfig
At this point you'll need to edit .config to match below:
CONFIG_LOCALVERSION="-g814e0a1 "
CONFIG_LOCALVERSION_AUTO=n
Modify Makefile so it starts with this:
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 32
EXTRAVERSION = .17
Continue as follows:
$ ARCH=arm make prepare
$ ARCH=arm make scripts
$ cd ..

(thanks FatTire and dpw13_)
then
$ # The following line assumes the CodeSourcery cross-compiler
$ CROSS_COMPILE=/opt/arm-2008q3/bin/arm-none-eabi- ARCH=arm make KDIR=[KERNEL SOURCE FROM WIKI] DOSTUFF=0
Copy to a place on your G2 (or other device).
On the G2 (in a root shell):
g2# dmesg -c
g2# rmmod module.ko
g2# insmod module.ko
g2# dmesg
Test and make sure it doesn't blow up and the printed (in dmesg) addresses look sane (not 0 or fffx whatever) Then proceed to build the working version:
$ CROSS_COMPILE=/opt/arm-2008q3/bin/arm-none-eabi- ARCH=arm make KDIR=[KERNEL SOURCE FROM WIKI] clean
$ CROSS_COMPILE=/opt/arm-2008q3/bin/arm-none-eabi- ARCH=arm make KDIR=[KERNEL SOURCE FROM WIKI] DOSTUFF=1
Now follow the same instructions to test.
