Run this after upgrading to 7.10

[H.axen]

The kernel flavor for PlayStation 3 systems has changed from powerpc64-smp to cell. Users upgrading their PlayStation 3 from Ubuntu 7.04 to 7.10 should run this before or after the upgrade:

$ sudo apt-get remove linux-image-powerpc64-smp linux-powerpc64-smp linux-restricted-modules-powerpc64-smp

$ sudo apt-get install linux-cell

In addition, the block device names have changed from the normal
/dev/sdX naming to /dev/ps3dX (e.g. /dev/sda1 will now be known as /dev/ps3da1). Standard installs should not be affected by this, since they use UUID naming. However, if you changed /etc/fstab to refer to hardcoded device names, you will need to adjust these for the new kernel.
