Download kernel 2.6.19 source
From JLiMe.com
Get v2.6.19 diff from here and apply against 2.6.19 (kernel.org)
Save both into folder of your choice (we assume /home/user/folder as an example):
cd /home/user/folder
tar -xzvf linux-2.6.19.tar.gz
cd linux-2.6.19
patch -p1 < ../v2-6-19.diff
cp config-hp(6/7/..) .config
export PATH=/directory/to/crosscompiler:$PATH
make ARCH=(arm/sh) CROSS_COMPILE=my-cross-gnu- zImage
make ARCH=(arm/sh) CROSS_COMPILE=my-cross-gnu- modules
make ARCH=(arm/sh) CROSS_COMPILE=my-cross-gnu- modules_install
You should now have your finished kernel inside linux-2.6.19/arch/(arm/sh)/boot/zImage and your modules extracted to /lib/modules/linux-2.6.19-hpc.
cp zImage to compact flash card (windows partition)
and modules to ext2 partition (should end up at /lib/modules/linux-2.6.19-hpc).
