As the title suggests, I decided to get Ubuntu 8.10 working on my MacBook Pro.
My aim, for a long time, has been to get linux running well on a Mac.
These mods are documented here.
The process is long and not suitable for beginers. I thought that these changes could be turned into a script that would work for most users that are dual/multi-booting their Mac.
The scripts can be found on a Ubuntu post that I just posted.
