Step by step instructions

Get the 2.6.26 kernel sources

cd /usr/src

wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.26.tar.bz2

tar -xjf linux-2.6.26.tar.bz2

rm linux

ln -s linux-2.6.26 linux

Download and apply the working PHC patch

wget http://howflow.com/trick/file/324/linux-phc-kernel-vanilla-2.6.26-aroedl.patch

cd linux

# This is the dry run. Make sure that it doesn't return an error message:
patch --dry-run -p1 <../linux-phc-kernel-vanilla-2.6.26-aroedl.patch

patch -p1 <../linux-phc-kernel-vanilla-2.6.26-aroedl.patch

Now you can build and install your kernel as usual.
