Booting Debian netinstall with petitboot from USB

I used a netboot image of Debian for installation: http://d-i.debian.org/daily-images/powerpc/daily/powerpc64/netboot/
Download vmlinux and initrd.gz and store it on a USB device
Mount the USB device with petitboot on /mnt/usb

That's how i booted Debian netinstall from petitboot:

kexec -l /mnt/usb/vmlinux --initrd=/mnt/usb/initrd.gz --append="root=/dev/ps3da1 video=720p"
sync
kexec -e
swapoff -a

Installing Debian on internal HDD

The problem with the default Debian Installer is that it uses the default SONY ps3disk block device driver to access HDD. This driver tries to use the first accessible HDD region for installation, and in petitboot booted with GameOS rights the first accessible HDD region will be the one owned by GameOS (UFS2), so be carefull or you will install your Linux on GameOS HDD region.
To fix this i patched HV temporarily and disabled access to all HDD regiosn except the one for Linux during Debian installation.
In the next days i will try to recompile the Debian Squeeze Installer and replace the default SONY ps3disk device driver with my own which i already tested on my PS3 Linux successfully.
