The wiki you linked to already gives a recipe for compiling that kernel:

Uncompress "/eTRAYz_Keren.tbz2" into some temp folder. Execure "build-target-kernel.sh" to compile this kernel and modules. When completed, kernel.tbz2 will be generated.
Unfortunately this does more than necessary.
Get yourself a Linux computer, on an Intel (-compatible) platform. Linux in a virtual machine is fine. A GUI is not needed, but it won't hurt. Open a commandprompt, and type
Code:
# Create and enter folder to contain it all:
mkdir e-trayz
cd e-trayz
# Download and extract GPL sources:
wget http://gator884.hostgator.com/~xtreamer/eTRAYz-Kernl/eTRAYz_Kernel.tbz2
tar xf eTRAYz_Kernel.tbz2
# Some one-time initialization (due to this specific GPL package)
cp kernel-config-target kernel/.config
mkdir -p kernel/include/config
echo 2.6.24.4 > kernel/include/config/kernel.release
# Installing some needed stuff. (Assuming you use Ubuntu)
sudo apt-get update
sudo apt-get install gcc ncurses
# Some administration for the crosscompiler (has to be done each time in this directory)
export BUILD_DIR=` pwd `
# Build the kernel. Take some coffee, this can take several hours, depending on your computer and the kernel config
make -C kernel uImage
Now you can find the new kernel (uImage) in kernel/arch/arm/boot
You'll also need kernel modules, which can be made:
Code:
# Make sure we're in the right directory:
cd ~/e-trayz
# Some administration
export BUILD_DIR=` pwd `
make -C kernel modules
make -C kernel INSTALL_MOD_PATH=".." modules_install
Now you have your modules in lib/modules/2.6.24.4
These directory has to be copied to /lib/modules/2.6.24.4 in your Debian rootfs. I *think* you also need to copy the firmware directory to /lib/firmware in de Debian rootfs, as this contains firmware which might have to be uploaded to the NIC, during userland boot.
So far you have build kernel+modules, but I suppose these are identical to those you already have. Not very exciting. So you want to change the kernel config:
Code:
# Make sure we're in the right directory:
cd ~/e-trayz
# Some administration
export BUILD_DIR=` pwd `
make -C kernel menuconfig
Go nuts. It's a good idea to put something in "General setup->Local version", this will result in the modules installed in lib/modules/2.6.24.4-something. This way you can boot a different kernel (-build) by just offering a different uImage to the bootloader. It will find it's own modules.
After you've left menuconfig you can build the kernel and modules:
Code:
make -C kernel uImage
make -C kernel modules
make -C kernel INSTALL_MOD_PATH=".." modules_install
