Sure, both kernels are latest andy-tracking. The debug one is build with 
standard:
cd linux-26
mkdir GTA02
cp arch/arm/configs/gta02_packaging_config GTA02/.config
./build GTA02
./build GTA02 dummy

and i also strip modules so that they are not too big:

find  . -name *.ko -exec /opt/toolchains/arm920t-eabi/bin/arm-linux-strip -R 
.not -R .comment --strip-unneeded {} \;

The nodebug kernel is based on this config[1] and i build it like this:

make CROSS_COMPILE=/opt/toolchains/arm920t-eabi/bin/arm-linux- ARCH=arm

make CROSS_COMPILE=/opt/toolchains/arm920t-eabi/bin/arm-linux- ARCH=arm 
modules_install

/opt/toolchains/arm920t-eabi/bin/arm-linux-objcopy -O binary -R .note -R 
.comment -S arch/arm/boot/compressed/vmlinux linux.bin

mkimage -A arm -O linux -T kernel -C none -a 30008000 -e 30008000 -n "QtMoko" 
-d linux.bin uImage-GTA02.bin

It could be also needed to run depmod on Neo if the booted kernel cant find 
modules.

Regards

Radek
