Debian PS3 Installation

It is holiday time and so finally time to installing Debian onto the Sony PS3 box. The installation was smooth as most of the stuff is already documented. The Debian Installer has all the support needed, to install onto the Sony PS3. As of now the only thing not working perfectly is the boot loader. It seems to be taking default is the kernel that was booted last. Even if I change the default in /etc/kboot.conf, it still boots into the kernel that was booted last time.
